111-681: The Naturmuseum Senckenberg ( SMF ) is a museum of natural history , located in Frankfurt am Main . It is the second-largest of its kind in Germany. In 2010, almost 517,000 people visited the museum, which is owned by the Senckenberg Nature Research Society . Senckenberg's slogan is "world of biodiversity ". As of 2019, the museum exhibits 18 reconstructed dinosaurs. In 1763, Johann Christian Senckenberg donated 95,000 guilders –his entire fortune–to establish
222-520: A rib . In 2007, Gregory S. Paul split I. atherfieldensis into a new, separate genus, Mantellisaurus which has been generally accepted. In 2009 fragmentary iguanodontid material was described from upper Barremian Paris Basin deposits in Auxerre , Burgundy . While not definitively diagnosable to the genus/species level, the specimen shares "obvious morphological and dimensional affinities" with I. bernissartensis. In 2010, David Norman split
333-517: A combination of alcohol , arsenic , and 390 kilograms of shellac . This combination was intended to simultaneously penetrate the fossils (with alcohol), prevent the development of mold (with arsenic), and harden them (with shellac). The fossils entered a third round of conservation from 2003 until May 2007, when the shellac, hide glue and gelatine were removed and impregnated with polyvinyl acetate and cyanoacrylate and epoxy glues. Modern treatments of this problem typically involve either monitoring

In 1817, 32 Frankfurt citizens founded the non-profit Senckenberg Nature Research Society , German: Senckenberg Gesellschaft für Naturforschung (SGN), which is a member of the Leibniz Association . Soon after, Johann Georg Neuburg [ de ] donated his collection of bird and mammal specimens to the society. The Naturmuseum Senckenberg
555-463: A final layer of tin foil . Damage was repaired with papier-mâché . This treatment had the unintended effect of sealing in moisture and extending the period of damage. In 1932 museum director Victor van Straelen decided that the specimens had to be completely restored again to safeguard their preservation. From December 1935 to August 1936 the staff at the museum in Brussels treated the problem with
666-460: A firm creationist , opposed the early versions of evolutionary science (" transmutationism ") then being debated and used what he would soon coin as dinosaurs as a weapon in this conflict. With the paper describing Dinosauria, he scaled down dinosaurs from lengths of over 61 metres (200 feet), determined that they were not simply giant lizards, and put forward that they were advanced and mammal-like, characteristics given to them by God ; according to
777-478: A giant crocodile . In 1821 Mantell mentioned the find of herbivorous teeth and began to consider the possibility that a large herbivorous reptile was present in the strata. However, in his 1822 publication Fossils of the South Downs he as yet did not dare to suggest a connection between the teeth and his very incomplete skeleton, presuming that his finds presented two large forms, one carnivorous ("an animal of
888-667: A giant herbivore. In a new edition that year of his Recherches sur les Ossemens Fossiles Cuvier admitted his earlier mistake, leading to an immediate acceptance of Mantell, and his new saurian, in scientific circles. Mantell tried to corroborate his theory further by finding a modern-day parallel among extant reptiles. In September 1824 he visited the Royal College of Surgeons but at first failed to find comparable teeth. However, assistant-curator Samuel Stutchbury recognised that they resembled those of an iguana he had recently prepared, albeit twenty times longer. In recognition of
999-482: A key holding is a fossilized Psittacosaurus (specimen SMF R 4970) from Liaoning , China, with clear bristles around its tail and visible fossilized stomach contents. The specimen was first reported in 2002. The exact date and locality of the discovery within Liaoning is unknown. A controversial debate about the legal ownership arose. In 2021, researchers described its cloaca in more detail and found similarities with
1110-615: A large collection of animal, plant and geology exhibits from every epoch of Earth's history . Main attraction is a Diplodocus from Bone Cabin Quarry , Wyoming , donated by the American Museum of Natural History on the occasion of the present museum building's inauguration on 13 October 1907, The 18 m (59 ft) mounted skeleton with additions contains bones of three different sauropod genera ( Diplodocus and closely related Apatosaurus and Barosaurus ). As of 2022,
1221-587: A lifelike pose could be achieved during the mounting process. This specimen, along with several others, first opened for public viewing in an inner courtyard of the palace in July 1883. In 1891 they were moved to the Royal Museum of Natural History , where they are still on display; nine are displayed as standing mounts, and nineteen more are still in the Museum's basement. The exhibit makes an impressive display in

The letter was read to members of the Society at a meeting on 17 December, and a report was published in the Hampshire Telegraph the following Monday, 20 December, which announced the name, misspelled as "Iguanadon". Mantell formally published his findings on 10 February 1825, when he presented a paper on the remains to the Royal Society of London . A more complete specimen of
1443-476: A naturalist, studies the world by observing plants and animals directly. Because organisms are functionally inseparable from the environment in which they live and because their structure and function cannot be adequately interpreted without knowing some of their evolutionary history, the study of natural history embraces the study of fossils as well as physiographic and other aspects of the physical environment". A common thread in many definitions of natural history
1554-645: A new genus Delapparentia was named for a specimen in Spain that was originally thought to belong to I. bernissartensis . The previous identification was subsequently reaffirmed in a new analysis of individual variation in the Belgian specimens, finding that the Delapparentia specimen was within the range of I. bernissartensis . In 2015 a new species of Iguanodon , I. galvensis , was named based on material including 13 juvenile ( perinate ) individuals found in
1665-420: A new reptile exhibit addresses both the biodiversity of reptiles and amphibians and the topic of nature conservation. The museum houses many originals from the nearby Messel pit , Germany's first UNESCO World Natural Heritage Site , among them a predecessor to the modern horse that lived about 50 million years ago and stood less than 60 cm (24 in) tall. In 2015, researchers found an foal fetus in
1776-556: A part of science proper. In Victorian Scotland, the study of natural history was believed to contribute to good mental health. Particularly in Britain and the United States, this grew into specialist hobbies such as the study of birds , butterflies, seashells ( malacology / conchology ), beetles, and wildflowers; meanwhile, scientists tried to define a unified discipline of biology (though with only partial success, at least until
1887-401: A permanent exhibition in the upper level. Additionally, the museum owns a large and diverse collection of birds with 90,000 bird skins, 5,050 egg sets, 17,000 skeletons, and 3,375 spirit specimens (a specimen preserved in fluid). This is 75% of the known bird species, only a minor part is exhibited. Anaconda is one of the oldest and most popular exhibits. Since the remodeling finished in 2003,
1998-480: A quadruped, the animal's hands would have been held so that the palms faced each other, as shown by iguanodontian trackways and the anatomy of this genus's arms and hands. The three-toed pes ( foot ) of Iguanodon was relatively long, and when walking, both the hand and the foot would have been used in a digitigrade fashion (walking on the fingers and toes). The maximum speed of Iguanodon has been estimated at 24 km/h (15 mph), which would have been as
2109-546: A rhinoceros. Though the very next day Cuvier retracted, Lyell reported only the dismissal to Mantell, who became rather diffident about the issue. In 1824 Buckland described Megalosaurus and was on that occasion invited to visit Mantell's collection. Seeing the bones on 6 March he agreed that these were of some giant saurian—though still denying it was a herbivore. Emboldened nevertheless, Mantell again sent some teeth to Cuvier, who answered on 22 June 1824 that he had determined that they were reptilian and quite possibly belonged to
2220-587: A rough margin that was likely covered and lengthened by a keratinous material to form a cropping beak for biting off twigs and shoots . Its food gathering would have been aided by its flexible little finger, which could have been used to manipulate objects, unlike the other fingers. Exactly what Iguanodon ate with its well-developed jaws is not known. The size of the larger species, such as I. bernissartensis , would have allowed them access to food from ground level to tree foliage at 4–5 metres (13–16 ft) high. A diet of horsetails , cycads , and conifers
2331-457: A similar animal was discovered in a quarry in Maidstone , Kent , in 1834 (lower Lower Greensand Formation), which Mantell soon acquired. He was led to identify it as an Iguanodon based on its distinctive teeth. The Maidstone slab (NHMUK PV OR 3791) was used in the first skeletal reconstructions and artistic renderings of Iguanodon , but due to its incompleteness, Mantell made some mistakes,
SECTION 20
#17327873837332442-683: A topic of study as new species are named or long-standing ones reassigned to other genera. In 1878 new, far more complete remains of Iguanodon were discovered in Belgium and studied by Louis Dollo . These were given the new species I. bernissartensis. In the early 21st century it became understood that the remains referred to as Iguanodon in England belonged to four different species (including I. bernissartensis ) that were not closely related to each other, which were subsequently split off into Mantellisaurus , Barilium and Hypselospinus . It
2553-470: A type of observation and a subject of study, it can also be defined as a body of knowledge, and as a craft or a practice, in which the emphasis is placed more on the observer than on the observed. Definitions from biologists often focus on the scientific study of individual organisms in their environment, as seen in this definition by Marston Bates: "Natural history is the study of animals and Plants—of organisms. ... I like to think, then, of natural history as
2664-607: Is a cross-discipline umbrella of many specialty sciences; e.g., geobiology has a strong multidisciplinary nature. The meaning of the English term "natural history" (a calque of the Latin historia naturalis ) has narrowed progressively with time, while, by contrast, the meaning of the related term "nature" has widened (see also History below). In antiquity , "natural history" covered essentially anything connected with nature , or used materials drawn from nature, such as Pliny
2775-752: Is a genus of iguanodontian dinosaur . While many species found worldwide have been classified in the genus Iguanodon , dating from the Late Jurassic to Early Cretaceous , taxonomic revision in the early 21st century has defined Iguanodon to be based on one well-substantiated species: I. bernissartensis , which lived during the Barremian to early Aptian ages of the Early Cretaceous in Belgium , Germany , England , and Spain , between about 126 and 122 million years ago. Iguanodon

Natural history Natural history is a domain of inquiry involving organisms , including animals , fungi , and plants , in their natural environment , leaning more towards observational than experimental methods of study. A person who studies natural history
2997-460: Is also echoed by H.W. Greene and J.B. Losos: "Natural history focuses on where organisms are and what they do in their environment, including interactions with other organisms. It encompasses changes in internal states insofar as they pertain to what organisms do". Some definitions go further, focusing on direct observation of organisms in their environments, both past and present, such as this one by G.A. Bartholomew: "A student of natural history, or
3108-411: Is called a naturalist or natural historian . Natural history encompasses scientific research but is not limited to it. It involves the systematic study of any category of natural objects or organisms, so while it dates from studies in the ancient Greco-Roman world and the mediaeval Arabic world , through to European Renaissance naturalists working in near isolation, today's natural history
3219-674: Is estimated to have measured about 9 metres (30 feet) long as an adult, with some specimens possibly as long as 13 metres (43 feet), although this is likely an overestimate, given that the maximum body length of I. bernissartensis is reported to be 11 m (36 ft). Although Gregory S. Paul suggested a body mass of 3.08 metric tons (3.40 short tons) on average, constructing a 3D mathematical model and employing allometry -based estimate suggests an I. bernissartensis close to 8 m (26 ft) long (smaller than average) weighs close to 3.8 metric tons (4.2 short tons) in body mass. Specimens of relatively large individuals have been reported in
3330-417: Is not conclusive, though. Whatever its exact diet, due to its size and abundance, Iguanodon is regarded as a dominant medium to large herbivore for its ecological communities . In England, this included the small predator Aristosuchus , larger predators Eotyrannus , Baryonyx , and Neovenator , low-feeding herbivores Hypsilophodon and Valdosaurus , fellow "iguanodontid" Mantellisaurus ,
3441-494: Is not on display. The fossil arrived in New Zealand following the move of Gideon Mantell's son Walter there; after the elder Mantell's death, his fossils went to Walter. Only two species assigned to Iguanodon are still considered to be valid. One of the first details noted about Iguanodon was that it had the teeth of a herbivorous reptile, although there has not always been consensus on how it ate. As Mantell noted,

3552-617: Is one of the first dinosaur genera to have been named, numerous species have been assigned to it. While never becoming the wastebasket taxon several other early genera of dinosaurs (such as Megalosaurus ) became, Iguanodon has had a complicated history, and its taxonomy continues to undergo revisions. Although Gregory Paul recommended restricting I. bernissartensis to the famous sample from Bernissart, ornithopod workers like Norman and McDonald have disagreed with Paul's recommendations, except exercising caution when accepting records of Iguanodon from France and Spain as valid. I. anglicus
3663-399: Is the inclusion of a descriptive component, as seen in a recent definition by H.W. Greene: "Descriptive ecology and ethology".

These include "Natural History Field Notes" of Biotropica , "The Scientific Naturalist" of Ecology , "From the Field" of Waterbirds , and
3885-669: The Camarillas Formation near Galve, Spain. In 2017 a new study was done of I. galvensis, with further evidence of distinctiveness from I. bernissartensis including several new autapomorphies . It was also found that the Delapparentia holotype (which is also from the Camarillas Formation) was not distinguishable from either I. bernissartensis or I. galvensis . Iguanodon were bulky herbivores that could shift from bipedality to quadrupedality . The only well-supported species, I. bernissartensis ,
3996-477: The Industrial Revolution prompted the development of geology to help find useful mineral deposits. Modern definitions of natural history come from a variety of fields and sources, and many of the modern definitions emphasize a particular aspect of the field, creating a plurality of definitions with a number of common themes among them. For example, while natural history is most often defined as

In modern terms, natural philosophy roughly corresponded to modern physics and chemistry , while natural history included the biological and geological sciences. The two were strongly associated. During the heyday of

From the ancient Greeks until the work of Carl Linnaeus and other 18th-century naturalists, a major concept of natural history was the scala naturae or Great Chain of Being , an arrangement of minerals, vegetables, more primitive forms of animals, and more complex life forms on a linear scale of supposedly increasing perfection, culminating in our species. Natural history

A replica of one of these is on display at the Oxford University Museum of Natural History and at the Sedgwick Museum in Cambridge. Most of the remains were referred to a new species, I. bernissartensis , a larger and much more robust animal than the English remains had yet revealed. One specimen, IRSNB 1551, was at first referred to

Carpenter and Ishida in 2010 named Proplanicoxa, Torilion and Sellacoxa while Gregory S. Paul in 2012 named Darwinsaurus , Huxleysaurus and Mantellodon and Macdonald et al. in 2012 named Kukufeldia . These species named after Norman 2010 are not considered valid and are considered various junior synonyms of Mantellisaurus , Barilium and Hypselospinus. In 2011,

4662-401: The armoured herbivore Polacanthus , and sauropods like Pelorosaurus . Early fossil remains were fragmentary, which led to much speculation on the posture and nature of Iguanodon . Iguanodon was initially portrayed as a quadrupedal horn-nosed beast. However, as more bones were discovered, Mantell observed that the forelimbs were much smaller than the hindlimbs. His rival Owen was of

The giraffe-tongue idea has also been incorrectly attributed to Dollo via a broken lower jaw. The skull was structured in such a way that as it closed, the bones holding the teeth in the upper jaw would bow out. This would cause the lower surfaces of

Still, the traditions of natural history continue to play a part in the study of biology, especially ecology (the study of natural systems involving living organisms and the inorganic components of the Earth's biosphere that support them), ethology (the scientific study of animal behavior), and evolutionary biology (the study of the relationships between life forms over very long periods of time), and re-emerges today as integrative organismal biology. Amateur collectors and natural history entrepreneurs played an important role in building

In recent times such observations contribute to how conservation priorities are determined. Mental health benefits can ensue, as well, from regular and active observation of chosen components of nature, and these reach beyond the benefits derived from passively walking through natural areas.

A new species that would become the subject of much study and taxonomic controversy, I. atherfieldensis , was named in 1925 by R. W. Hooley , for a specimen collected at Atherfield Point on the Isle of Wight . Iguanodon was not part of the initial work of the dinosaur renaissance that began with the description of Deinonychus in 1969, but it

This organ was more or less straight, as shown by the skeletons he was excavating, and the presence of ossified tendons. In fact, to get the bend in the tail for a more wallaby or kangaroo -like posture, the tail would have had to be broken. With its correct, straight tail and back,
5883-799: The Senckenberg Museum was erected between 1904 and 1907 by Ludwig Neher [ de ] outside of the center of Frankfurt in the same area as the Johann Wolfgang Goethe University , which was founded in 1914. The museum is owned and operated by the Senckenberg Nature Research Society. The exhibition area covers 6,000 m (65,000 sq ft).

Essentially, the modern concept of Iguanodontidae currently includes only Iguanodon . Groups like Iguanodontoidea are still used as unranked clades in
6216-449: The animal would have walked with its body held horizontal to the ground, arms in place to support the body if needed. In the 21st century, Iguanodon material has been used in the search for dinosaur biomolecules . In research by Graham Embery et al., Iguanodon bones were processed to look for remnant proteins . In this research, identifiable remains of typical bone proteins, such as phosphoproteins and proteoglycans , were found in

At least 15 individuals, from 2 to 8 metres (6 ft 7 in to 26 ft 3 in) long, have been found here, most of the individuals belong to the related Mantellisaurus (described as I. atherfieldensis , at that time believed to be another species of Iguanodon ). but some are of I. bernissartensis. One major revision to Iguanodon brought by

This family traditionally has been something of a wastebasket taxon , including ornithopods that were neither hypsilophodontids or hadrosaurids. In practice, animals like Callovosaurus , Camptosaurus , Craspedodon , Kangnasaurus , Mochlodon , Muttaburrasaurus , Ouranosaurus , and Probactrosaurus were usually assigned to this family. With

These definitions explicitly include the arts in
7437-710: The emergence of professional biological disciplines and research programs. Particularly in the 19th century, scientists began to use their natural history collections as teaching tools for advanced students and the basis for their own morphological research. The term "natural history" alone, or sometimes together with archaeology, forms the name of many national, regional, and local natural history societies that maintain records for animals (including birds (ornithology), insects ( entomology ) and mammals (mammalogy)), fungi ( mycology ), plants (botany), and other organisms. They may also have geological and microscopical sections. Examples of these societies in Britain include

It is known from his notebooks that Mantell first acquired large fossil bones from the quarry at Whitemans Green in 1820. Because also theropod teeth were found, thus belonging to carnivores, he at first interpreted these bones, which he tried to combine into a partial skeleton, as those of

Furthermore, he admitted in 1851 that he himself had found the teeth, although he had previously stated in 1827 and 1833 that Mrs. Mantell had indeed found
7992-559: The hand is relatively immobile, with the three central fingers grouped together, bearing hoof -like phalanges , and able to hyperextend . This would have allowed them to bear weight. The wrist is also relatively immobile, and the arms and shoulder bones robust. These features all suggest that the animal spent time on all fours. Furthermore, it appears that Iguanodon became more quadrupedal as it got older and heavier; juvenile I. bernissartensis have shorter arms than adults (60% of hindlimb length versus 70% for adults). When walking as
8103-403: The holotype of a separate species Mantellodon carpenteri by Paul (2012), but this is considered dubious and it is generally considered a specimen of Mantellisaurus At the same time, tension began to build between Mantell and Richard Owen , an ambitious scientist with much better funding and society connections in the turbulent worlds of Reform Act -era British politics and science. Owen,
8214-409: The humidity of fossil storage, or, for fresh specimens, preparing a special coating of polyethylene glycol that is then heated in a vacuum pump, so that moisture is immediately removed and pore spaces are infiltrated with polyethylene glycol to seal and strengthen the fossil. Dollo's specimens allowed him to show that Owen's prehistoric pachyderms were not correct for Iguanodon . He instead modelled
8325-463: The length of the legs) and robust, with rather inflexible hands built so that the three central fingers could bear weight. The thumbs were conical spikes that stuck out away from the three main digits. In early restorations, the spike was placed on the animal's nose. Later fossils revealed the true nature of the thumb spikes, although their exact function is still debated. They could have been used for defense, or for foraging for food. The little finger
8436-525: The line to the flat-headed hadrosaurines , and Ouranosaurus on the line to the crested lambeosaurines , but his proposal has been rejected. The cladogram below follows an analysis by Andrew McDonald, 2012. Rhabdodontidae Tenontosaurus Dryosauridae Camptosaurus Uteodon Hippodraco Theiophytalia Iguanacolossus Lanzhousaurus Kukufeldia Barilium Iguanodon Hadrosauroidea (including Mantellisaurus , and Xuwulong ) Because Iguanodon
8547-468: The living animal, including feeding, movement, and social behaviour. As one of the first scientifically well-known dinosaurs, Iguanodon has occupied a small but notable place in the public's perception of dinosaurs, its artistic representation changing significantly in response to new interpretations of its remains. The discovery of Iguanodon has long been accompanied by a popular legend . The story goes that Gideon Mantell 's wife, Mary Ann , discovered
8658-452: The mine for palaeontology, and Otto Jaekel was sent from Berlin to supervise. Just as the first fossiliferous layer was about to be uncovered, however, the German army surrendered and had to withdraw. Further attempts to reopen the mine were hindered by financial problems and were stopped altogether in 1921 when the mine flooded. Research on Iguanodon decreased during the early part of
8769-597: The most famous of which was the placement of what he thought was a horn on the nose. The discovery of much better specimens in later years revealed that the horn was actually a modified thumb. Still encased in rock, the Maidstone skeleton is currently displayed at the Natural History Museum in London . The borough of Maidstone commemorated this find by adding an Iguanodon as a supporter to their coat of arms in 1949. This specimen has become linked with
8880-503: The name I. mantelli , a species named in 1832 by Christian Erich Hermann von Meyer in place of I. anglicus , but it actually comes from a different formation than the original I. mantelli / I. anglicus material. The Maidstone specimen, also known as Gideon Mantell's "Mantel-piece", and formally labelled NHMUK 3741 was subsequently excluded from Iguanodon . It is classified as cf. Mantellisaurus by McDonald (2012); as cf. Mantellisaurus atherfieldensis by Norman (2012); and made
8991-433: The name suggests, but much larger and more closely packed. Unlike hadrosaurids, which had columns of replacement teeth, Iguanodon only had one replacement tooth at a time for each position. The upper jaw held up to 29 teeth per side, with none at the front of the jaw , and the lower jaw 25; the numbers differ because teeth in the lower jaw are broader than those in the upper. Because the tooth rows are deeply inset from
9102-493: The nebulous, gracile I. mantelli , but is currently referred to Mantellisaurus atherfieldensis . The skeletons were some of the first complete dinosaur skeletons known. Found with the dinosaur skeletons were the remains of plants, fish, and other reptiles, including the crocodyliform Bernissartia . The science of conserving fossil remains was in its infancy, and new techniques had to be improvised to deal with what soon became known as " pyrite disease". Crystalline pyrite in
9213-476: The opinion it was a stumpy creature with four pillar-like legs. The job of overseeing the first lifesize reconstruction of dinosaurs was initially offered to Mantell, who declined due to poor health, and Owen's vision subsequently formed the basis on which the sculptures took shape. Its bipedal nature was revealed with the discovery of the Bernissart skeletons. However, it was depicted in an upright posture, with
9324-568: The outside of the jaws, and because of other anatomical details, it is believed that, as with most other ornithischians, Iguanodon had some sort of cheek -like structure, muscular or non-muscular, to retain food in the mouth. Iguanodon gives its name to the unranked clade Iguanodontia , a very populous group of ornithopods with many species known from the Middle Jurassic to the Late Cretaceous . Aside from Iguanodon ,
9435-430: The remains he was working with were unlike any modern reptile, especially in the toothless, scoop-shaped form of the lower jaw symphysis , which he found best compared to that of the two-toed sloth and the extinct ground sloth Mylodon . He also suggested that Iguanodon had a prehensile tongue which could be used to gather food, like a giraffe . More complete remains have shown this to be an error; for example,
9546-552: The resemblance of the teeth to those of the iguana, Mantell decided to name his new animal Iguanodon or 'iguana-tooth', from iguana and the Greek word ὀδών ( odon , odontos or 'tooth'). Based on isometric scaling , he estimated that the creature might have been up to 18 metres (59 feet) long, more than the 12-metre (39 ft) length of Megalosaurus . His initial idea for a name was Iguana-saurus ('Iguana lizard'), but his friend William Daniel Conybeare suggested that that name
9657-412: The scientific literature, though many traditional iguanodontids are now included in the superfamily Hadrosauroidea . Iguanodon lies between Camptosaurus and Ouranosaurus in cladograms, and is probably descended from a camptosaur-like animal. At one point, Jack Horner suggested, based mostly on skull features , that hadrosaurids actually formed two more distantly related groups, with Iguanodon on
9768-454: The skeletal mounts after the cassowary and wallaby , and put the spike that had been on the nose firmly on the thumb . His reconstruction would prevail for a long period of time, but would later be discounted. Excavations at the quarry were stopped in 1881, although it was not exhausted of fossils, as recent drilling operations have shown. During World War I , when the town was occupied by German forces , preparations were made to reopen
9879-454: The skeletons and in 1882 Louis Dollo reconstructed them. At least 38 Iguanodon individuals were uncovered, most of which were adults. In 1882, the holotype specimen of I. bernissartensis became one of the first ever dinosaur skeletons mounted for display. It was put together in a chapel at the Palace of Charles of Lorraine using a series of adjustable ropes attached to scaffolding so that
9990-451: The study of life at the level of the individual—of what plants and animals do, how they react to each other and their environment, how they are organized into larger groupings like populations and communities" and this more recent definition by D.S. Wilcove and T. Eisner: "The close observation of organisms—their origins, their evolution, their behavior, and their relationships with other species". This focus on organisms in their environment
10101-524: The system of the Swedish naturalist Carl Linnaeus . The British historian of Chinese science Joseph Needham calls Li Shizhen "the 'uncrowned king' of Chinese naturalists", and his Bencao gangmu "undoubtedly the greatest scientific achievement of the Ming". His works translated to many languages direct or influence many scholars and researchers. A significant contribution to English natural history
10212-440: The tail dragging along the ground, acting as the third leg of a tripod. During his re-examination of Iguanodon , David Norman was able to show that this posture was unlikely, because the long tail was stiffened with ossified tendons. To get the tripodal pose, the tail would literally have to be broken. Putting the animal in a horizontal posture makes many aspects of the arms and pectoral girdle more understandable. For example,
10323-491: The understanding of the time, they could not have been "transmuted" from reptiles to mammal-like creatures. In 1849, a few years before his death in 1852, Mantell realised that iguanodonts were not heavy, pachyderm -like animals, as Owen was putting forward, but had slender forelimbs. However, since his passing left him unable to participate in the creation of the Crystal Palace dinosaur sculptures , Owen's vision of
10434-460: The upper jaw teeth to rub against the upper surface of the lower jaw's teeth, grinding anything caught in between and providing an action that is the rough equivalent of mammalian chewing . Because the teeth were always replaced, the animal could have used this mechanism throughout its life, and could eat tough plant material. Additionally, the front ends of the animal's jaws were toothless and tipped with bony nodes, both upper and lower, providing
10545-475: The world works by providing the empirical foundation of natural sciences, and it contributes directly and indirectly to human emotional and physical health, thereby fostering healthier human communities. It also serves as the basis for all conservation efforts, with natural history both informing the science and inspiring the values that drive these. As a precursor to Western science , natural history began with Aristotle and other ancient philosophers who analyzed
10656-613: The world's large natural history collections, such as the Natural History Museum, London , and the National Museum of Natural History in Washington, DC. Three of the greatest English naturalists of the 19th century, Henry Walter Bates , Charles Darwin , and Alfred Russel Wallace —who knew each other—each made natural history travels that took years, collected thousands of specimens, many of them new to science, and by their writings both advanced knowledge of "remote" parts of
10767-564: The world. The plurality of definitions for this field has been recognized as both a weakness and a strength, and a range of definitions has recently been offered by practitioners in a recent collection of views on natural history. Prior to the advent of Western science humans were engaged and highly competent in indigenous ways of understanding the more-than-human world that are now referred to as traditional ecological knowledge . 21st century definitions of natural history are inclusive of this understanding, such as this by Thomas Fleischner of
10878-799: The world—the Amazon basin , the Galápagos Islands , and the Indonesian Archipelago , among others—and in so doing helped to transform biology from a descriptive to a theory-based science. The understanding of "Nature" as "an organism and not as a mechanism" can be traced to the writings of Alexander von Humboldt (Prussia, 1769–1859). Humboldt's copious writings and research were seminal influences for Charles Darwin, Simón Bolívar , Henry David Thoreau , Ernst Haeckel , and John Muir . Natural history museums , which evolved from cabinets of curiosities , played an important role in
10989-430: Was a large, bulky herbivore , measuring up to 9–11 metres (30–36 ft) in length and 4.5 metric tons (5.0 short tons) in body mass. Distinctive features include large thumb spikes, which were possibly used for defense against predators , combined with long prehensile fifth fingers able to forage for food. The genus was named in 1825 by English geologist Gideon Mantell , based on fossil specimens found in England and
11100-724: Was also found that the originally described type species of Iguanodon, I. anglicus is now a nomen dubium , and not valid. Thus the name " Iguanodon " became fixed around the well known species based primarily on the Belgian specimens. In 2015, a second valid species, I. galvensis , was named, based on fossils found in the Iberian Peninsula. Scientific understanding of Iguanodon has evolved over time as new information has been obtained from fossils . The numerous specimens of this genus, including nearly complete skeletons from two well-known bone beds , have allowed researchers to make informed hypotheses regarding many aspects of
11211-741: Was basically static through the Middle Ages in Europe—although in the Arabic and Oriental world, it proceeded at a much brisker pace. From the 13th century, the work of Aristotle was adapted rather rigidly into Christian philosophy , particularly by Thomas Aquinas , forming the basis for natural theology . During the Renaissance, scholars (herbalists and humanists, particularly) returned to direct observation of plants and animals for natural history, and many began to accumulate large collections of exotic specimens and unusual monsters . Leonhart Fuchs
11322-505: Was completed, he held a banquet for twenty inside it. The largest find of Iguanodon remains to that date occurred on 28 February 1878 in a coal mine at Bernissart in Belgium , at a depth of 322 m (1,056 ft), when two mineworkers, Jules Créteur and Alphonse Blanchard, accidentally hit on a skeleton that they initially took for petrified wood . With the encouragement of Alphonse Briart , supervisor of mines at nearby Morlanwelz , Louis de Pauw on 15 May 1878 started to excavate
11433-630: Was elongated and dextrous, and could have been used to manipulate objects. The phalangeal formula is 2-3-3-2-4, meaning that the innermost finger (phalange) has two bones, the next has three, etc. The legs were powerful, but not built for running, and each foot had three toes. The backbone and tail were supported and stiffened by ossified tendons , which were tendons that turned to bone during life (these rod-like bones are usually omitted from skeletal mounts and drawings). These animals had large, tall but narrow skulls, with toothless beaks probably covered with keratin , and teeth like those of iguanas , as
11544-489: Was founded in 1821, just four years later. Initially located near the Eschenheimer Turm , the museum moved to a new building on Senckenberganlage in 1907. In 1896 a mummified Egyptian child in their collection (inventory number ÄS 18) was the subject of the first mummy X-ray. During World War II , the building was partly destroyed. However, the exhibits had been evacuated before. The neo-baroque building housing
11655-421: Was given the species name I. anglicus. Iguanodon was the second type of dinosaur formally named based on fossil specimens, after Megalosaurus . Together with Megalosaurus and Hylaeosaurus , it was one of the three genera originally used to define Dinosauria . The genus Iguanodon belongs to the larger group Iguanodontia , along with the duck-billed hadrosaurs. The taxonomy of this genus continues to be
11766-402: Was made by parson-naturalists such as Gilbert White , William Kirby , John George Wood , and John Ray , who wrote about plants, animals, and other aspects of nature. Many of these men wrote about nature to make the natural theology argument for the existence or goodness of God. Since early modern times, however, a great number of women made contributions to natural history, particularly in
11877-487: Was more applicable to the iguana itself, so a better name would be Iguanoides ('Iguana-like') or Iguanodon . He neglected to add a specific name to form a proper binomial , but one was supplied in 1829 by Friedrich Holl: I. anglicum , which was later emended to I. anglicus . Mantell sent a letter detailing his discovery to the local Portsmouth Philosophical Society in December 1824, several weeks after settling on
11988-479: Was not neglected for long. David B. Weishampel 's work on ornithopod feeding mechanisms provided a better understanding of how it fed, and David B. Norman 's work on numerous aspects of the genus has made it one of the best-known dinosaurs. In addition, a further find of numerous disarticulated Iguanodon bones in Nehden, Nordrhein-Westphalen , Germany , has provided evidence for gregariousness in this genus, as
12099-405: Was one of the three founding fathers of botany, along with Otto Brunfels and Hieronymus Bock . Other important contributors to the field were Valerius Cordus , Konrad Gesner ( Historiae animalium ), Frederik Ruysch , and Gaspard Bauhin . The rapid increase in the number of known organisms prompted many attempts at classifying and organizing species into taxonomic groups , culminating in
12210-465: Was suggested by David Norman, although iguanodonts in general have been tied to the advance of angiosperm plants in the Cretaceous due to the dinosaurs' inferred low-browsing habits. Angiosperm growth, according to this hypothesis , would have been encouraged by iguanodont feeding because gymnosperms would be removed, allowing more space for the weed -like early angiosperms to grow. The evidence
12321-595: Was the original type species , but the lectotype was based on a single tooth and only partial remains of the species have been recovered since. In March 2000, the International Commission on Zoological Nomenclature changed the type species to the much better known I. bernissartensis , with the new holotype being IRSNB 1534. The original Iguanodon tooth is held at Te Papa Tongarewa , the national museum of New Zealand in Wellington , although it
