86-485: Dino Crisis takes place on a fictional location known as Ibis Island in the year 2009. The Secret Operation Raid Team (SORT) has sent an agent, Tom, to investigate a research facility. During the recon mission, he learns that Dr. Edward Kirk, a world-renowned scientist who was reported dead three years ago, is leading a secret weapons project within the facility. SORT sends four agents (Regina, Gail, Rick, and Cooper) to acquire Kirk and return him to custody. The team arrives on

172-403: A T. rex toe exposed above ground, making him the youngest person to discover a Tyrannosaurus . The specimen, dubbed Bucky in honor of its discoverer, was a young adult, 3.0 metres (10 ft) tall and 11 metres (35 ft) long. Bucky is the first Tyrannosaurus to be found that preserved a furcula (wishbone). Bucky is permanently displayed at The Children's Museum of Indianapolis . In

258-642: A scavenger . The question of whether Tyrannosaurus was an apex predator or a pure scavenger was among the longest debates in paleontology . Most paleontologists today accept that Tyrannosaurus was both an active predator and a scavenger. Specimens of Tyrannosaurus rex include some that are nearly complete skeletons. Soft tissue and proteins have been reported in at least one of these specimens. The abundance of fossil material has allowed significant research into many aspects of its biology, including its life history and biomechanics . The feeding habits, physiology , and potential speed of Tyrannosaurus rex are

344-557: A species : see Botanical name and Specific name (zoology) . The rules for the scientific names of organisms are laid down in the nomenclature codes , which allow each species a single unique name that, for animals (including protists ), plants (also including algae and fungi ) and prokaryotes ( bacteria and archaea ), is Latin and binomial in form; this contrasts with common or vernacular names , which are non-standardized, can be non-unique, and typically also vary by country and language of usage. Except for viruses ,

430-455: A broad postorbital and hourglass shaped nasals. Some of the more derived pantyrannosaurs lack nasal pneumaticity and have a lower humerus to femur ratio with their arms starting to see some reduction. Some pantyrannosaurs started developing an arctometatarsus. Eutyrannosaurs have a rough texture on their nasal bones and their mandibular fenestra is reduced externally. Tyrannosaurids lack kinetic skulls or special crests on their nasal bones, and have

516-800: A clade with fellow Asian tyrannosaurid Zhuchengtyrannus , with Lythronax being their sister taxon. A further study from 2016 by Steve Brusatte, Thomas Carr and colleagues, also indicates that Tyrannosaurus may have been an immigrant from Asia, as well as a possible descendant of Tarbosaurus . Below is the cladogram of Tyrannosauridae based on the phylogenetic analysis conducted by Loewen and colleagues in 2013.

The vertebral bodies of the torso were robust but with a narrow waist. Their undersides were keeled. The front sides were concave with a deep vertical trough. They had large pleurocoels. Their neural spines had very rough front and rear sides for

In Resident Evil 3: Nemesis , the player can unlock her outfit with a red wig as a bonus costume for Jill Valentine . Annie also " cosplays " as Regina in Super Ultra Dead Rising 3 Arcade Remix Hyper Edition EX Plus Alpha , a downloadable content for Dead Rising 3 . A figure of her

774-581: A fan asking if a new Dino Crisis title would release soon, to which they replied: "If a lot of people wish". A six-part manhua based on Dino Crisis ( 恐龍危機 ) was published in Hong Kong. It is a loose adaptation of the first Dino Crisis game, and was published by the Hong Kong–based company Jade Dynasty (玉皇朝). The series was produced by Tony Wong (黄玉郎). Regina has also appeared in the tactical role-playing video game Namco × Capcom , beginning on

860-483: A few subjects of debate. Its taxonomy is also controversial, as some scientists consider Tarbosaurus bataar from Asia to be a third Tyrannosaurus species, while others maintain Tarbosaurus is a separate genus. Several other genera of North American tyrannosaurids have also been synonymized with Tyrannosaurus . At present, two species of Tyrannosaurus are considered valid; the type species, T. rex , and

946-464: A lacrimal with a distinctive process on it. Tyrannosaurids also have an interfenestral strut that is less than half as big as the maxillary fenestra. It is quite likely that tyrannosauroids rose to prominence after the decline in allosauroid and megalosauroid diversity seen during the early stages of the Late Cretaceous. Below is a simple cladogram of general tyrannosauroid relationships that

1032-651: A later homonym of a validly published name is a nomen illegitimum or nom. illeg. ; for a full list refer to the International Code of Nomenclature for algae, fungi, and plants and the work cited above by Hawksworth, 2010. In place of the "valid taxon" in zoology, the nearest equivalent in botany is " correct name " or "current name" which can, again, differ or change with alternative taxonomic treatments or new information that results in previously accepted genera being combined or split. Prokaryote and virus codes of nomenclature also exist which serve as

For example, the World Register of Marine Species presently lists 8 genus-level synonyms for the sperm whale genus Physeter Linnaeus, 1758, and 13 for the bivalve genus Pecten O.F. Müller, 1776. Within the same kingdom, one generic name can apply to one genus only. However, many names have been assigned (usually unintentionally) to two or more different genera. For example,

1204-908: A mass estimation technique that extrapolates from the circumference of the femur, Scotty was estimated as the largest known specimen at 8.87 t (8.73 long tons; 9.78 short tons) in body mass. Not every adult Tyrannosaurus specimen recovered is as big. Historically average adult mass estimates have varied widely over the years, from as low as 4.5 t (4.4 long tons; 5.0 short tons), to more than 7.2 t (7.1 long tons; 7.9 short tons), with most modern estimates ranging between 5.4 and 8.0 t (5.3 and 7.9 long tons; 6.0 and 8.8 short tons). A 2024 study estimated based on allometry that world-record sized T. rex specimens (1 in 100,000 individuals) may have reached lengths and weights exceeding 15 m (49 ft) and 15,000 kg (33,000 lb) respectively, though no individuals close to this size have ever been found. The study also found that there

1290-456: A narrow snout, allowing unusually good binocular vision . The skull bones were massive and the nasals and some other bones were fused, preventing movement between them; but many were pneumatized (contained a "honeycomb" of tiny air spaces) and thus lighter. These and other skull-strengthening features are part of the tyrannosaurid trend towards an increasingly powerful bite, which easily surpassed that of all non-tyrannosaurids. The tip of

1376-630: A reconstructed skull displayed at the Museum of the Rockies . The 1990s saw numerous discoveries, with nearly twice as many finds as in all previous years, including two of the most complete skeletons found to date: Sue and Stan . Sue Hendrickson , an amateur paleontologist, discovered the most complete (approximately 85%) and largest Tyrannosaurus skeleton in the Hell Creek Formation on August 12, 1990. The specimen Sue, named after

1462-409: A reference for designating currently accepted genus names as opposed to others which may be either reduced to synonymy, or, in the case of prokaryotes, relegated to a status of "names without standing in prokaryotic nomenclature". An available (zoological) or validly published (botanical) name that has been historically applied to a genus but is not regarded as the accepted (current/valid) name for

1548-427: A taxon; however, the names published in suppressed works are made unavailable via the relevant Opinion dealing with the work in question. In botany, similar concepts exist but with different labels. The botanical equivalent of zoology's "available name" is a validly published name . An invalidly published name is a nomen invalidum or nom. inval. ; a rejected name is a nomen rejiciendum or nom. rej. ;

1634-455: A total of c. 520,000 published names (including synonyms) as at end 2019, increasing at some 2,500 published generic names per year. "Official" registers of taxon names at all ranks, including genera, exist for a few groups only such as viruses and prokaryotes, while for others there are compendia with no "official" standing such as Index Fungorum for fungi, Index Nominum Algarum and AlgaeBase for algae, Index Nominum Genericorum and

1720-549: Is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses . In binomial nomenclature , the genus name forms the first part of the binomial species name for each species within the genus. The composition of a genus is determined by taxonomists . The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including

In 2002, a skeleton nicknamed "Wyrex", discovered by amateur collectors Dan Wells and Don Wyrick, had 114 bones and was 38% complete. The dig was concluded over 3 weeks in 2004 by the Black Hills Institute with the first live online Tyrannosaurus excavation providing daily reports, photos, and video. In 2006, Montana State University revealed that it possessed

1978-401: Is now western North America , on what was then an island continent known as Laramidia . Tyrannosaurus had a much wider range than other tyrannosaurids . Fossils are found in a variety of rock formations dating to the latest Campanian - Maastrichtian ages of the late Cretaceous period , 72.7 to 66  million years ago . It was the last known member of the tyrannosaurids and among

2064-460: Is somewhat arbitrary. Although all species within a genus are supposed to be "similar", there are no objective criteria for grouping species into genera. There is much debate among zoologists about whether enormous, species-rich genera should be maintained, as it is extremely difficult to come up with identification keys or even character sets that distinguish all species. Hence, many taxonomists argue in favor of breaking down large genera. For instance,

2150-407: Is still among the largest known land predators, with its estimated bite force being the largest among all terrestrial animals. By far the largest carnivore in its environment, Tyrannosaurus rex was most likely an apex predator , preying upon hadrosaurs , juvenile armored herbivores like ceratopsians and ankylosaurs , and possibly sauropods . Some experts have suggested the dinosaur was primarily

2236-474: Is the type species , and the generic name is permanently associated with the type specimen of its type species. Should the specimen turn out to be assignable to another genus, the generic name linked to it becomes a junior synonym and the remaining taxa in the former genus need to be reassessed. In zoological usage, taxonomic names, including those of genera, are classified as "available" or "unavailable". Available names are those published in accordance with

2322-452: Is unknown and could well have varied between individuals but probably numbered at least forty. Sue was mounted with forty-seven of such caudal vertebrae. The neck of T. rex formed a natural S-shaped curve like that of other theropods. Compared to these, it was exceptionally short, deep and muscular to support the massive head. The second vertebra, the axis, was especially short. The remaining neck vertebrae were weakly opisthocoelous, i.e. with

2408-608: The Hell Creek Formation in Montana in 1902, comprising approximately 34 fossilized bones. Writing at the time Brown said "Quarry No. 1 contains the femur, pubes, humerus, three vertebrae and two undetermined bones of a large Carnivorous Dinosaur not described by Marsh . ... I have never seen anything like it from the Cretaceous ." Henry Fairfield Osborn , president of the American Museum of Natural History , named

2494-593: The Hell Creek Formation of Montana. This second track measures 72 centimeters (28 in) long, shorter than the track described by Lockley and Hunt. Whether or not the track was made by Tyrannosaurus is unclear, though Tyrannosaurus is the only large theropod known to have existed in the Hell Creek Formation. A set of footprints in Glenrock, Wyoming dating to the Maastrichtian stage of

2580-621: The International Code of Zoological Nomenclature ; the earliest such name for any taxon (for example, a genus) should then be selected as the " valid " (i.e., current or accepted) name for the taxon in question. Consequently, there will be more available names than valid names at any point in time; which names are currently in use depending on the judgement of taxonomists in either combining taxa described under multiple names, or splitting taxa which may bring available names previously treated as synonyms back into use. "Unavailable" names in zoology comprise names that either were not published according to

Totals for both "all names" and estimates for "accepted names" as held in the Interim Register of Marine and Nonmarine Genera (IRMNG) are broken down further in the publication by Rees et al., 2020 cited above. The accepted names estimates are as follows, broken down by kingdom: The cited ranges of uncertainty arise because IRMNG lists "uncertain" names (not researched therein) in addition to known "accepted" names;

The upper arm bone, the humerus, was short but robust. It had a narrow upper end with an exceptionally rounded head. The lower arm bones, the ulna and radius, were straight elements, much shorter than the humerus. The second metacarpal

2838-404: The platypus belongs to the genus Ornithorhynchus although George Shaw named it Platypus in 1799 (these two names are thus synonyms ) . However, the name Platypus had already been given to a group of ambrosia beetles by Johann Friedrich Wilhelm Herbst in 1793. A name that means two different things is a homonym . Since beetles and platypuses are both members of the kingdom Animalia,

2924-473: The French botanist Joseph Pitton de Tournefort (1656–1708) is considered "the founder of the modern concept of genera". The scientific name (or the scientific epithet) of a genus is also called the generic name ; in modern style guides and science, it is always capitalised. It plays a fundamental role in binomial nomenclature , the system of naming organisms , where it is combined with the scientific name of

3010-464: The Late Cretaceous and hailing from the Lance Formation were described by Scott Persons, Phil Currie and colleagues in 2016, and are believed to belong to either a juvenile T. rex or the dubious tyrannosaurid Nanotyrannus lancensis . From measurements and based on the positions of the footprints, the animal was believed to be traveling at a walking speed of around 2.8 to 5 miles per hour and

3096-437: The attachment of strong tendons. The sacral vertebrae were fused to each other, both in their vertebral bodies and neural spines. They were pneumatized. They were connected to the pelvis by transverse processes and sacral ribs. The tail was heavy and moderately long, in order to balance the massive head and torso and to provide space for massive locomotor muscles that attached to the thighbones. The thirteenth tail vertebra formed

3182-548: The auspices of Prof. Arthur Lakes near Golden, Colorado . In the early 1890s, John Bell Hatcher collected postcranial elements in eastern Wyoming . The fossils were believed to be from the large species Ornithomimus grandis (now Deinodon ) but are now considered T. rex remains. In 1892, Edward Drinker Cope found two vertebral fragments of a large dinosaur. Cope believed the fragments belonged to an "agathaumid" ( ceratopsid ) dinosaur, and named them Manospondylus gigas , meaning "giant porous vertebra", in reference to

However, this does not typically ascend more than one or two levels: the order to which dogs and wolves belong is Carnivora ("Carnivores"). The numbers of either accepted, or all published genus names is not known precisely; Rees et al., 2020 estimate that approximately 310,000 accepted names (valid taxa) may exist, out of

Various functions have been proposed for these foramina, such as a crocodile-like sensory system or evidence of extra-oral structures such as scales or potentially lips, with subsequent research on theropod tooth wear patterns supporting such a proposition. The vertebral column of Tyrannosaurus consisted of ten neck vertebrae, thirteen back vertebrae and five sacral vertebrae. The number of tail vertebrae

Dynamosaurus would later be honored by the 2018 description of another species of tyrannosaurid by Andrew McDonald and colleagues, Dynamoterror dynastes , whose name was chosen in reference to the 1905 name, as it had been a "childhood favorite" of McDonald's. From the 1910s through the end of the 1950s, Barnum's discoveries remained

Tyrannosaurs started out as small theropods; however at least some became larger by the Early Cretaceous . Tyrannosauroids are characterized by their fused nasals and dental arrangement. Pantyrannosaurs are characterized by unique features in their hips as well as an enlarged foramen in the quadrate,

The fossil collection was purchased by the Field Museum of Natural History at auction for $ 7.6 million, making it the most expensive dinosaur skeleton until the sale of Stan for $ 31.8 million in 2020. From 1998 to 1999, Field Museum of Natural History staff spent over 25,000 hours taking

3698-497: The earlier in age and more recently discovered T. mcraeensis . As the archetypal theropod, Tyrannosaurus has been one of the best-known dinosaurs since the early 20th century and has been featured in film, advertising, postal stamps, and many other media. A tooth from what is now documented as a Tyrannosaurus rex was found in July 1874 upon South Table Mountain (Colorado) by Jarvis Hall (Colorado) student Peter T. Dotson under

3784-427: The entire shaft of the element. The rear ischium was slender and straight, pointing obliquely to behind and below. In contrast to the arms, the hindlimbs were among the longest in proportion to body size of any theropod. In the foot, the metatarsus was "arctometatarsalian", meaning that the part of the third metatarsal near the ankle was pinched. The third metatarsal was also exceptionally sinuous. Compensating for

3870-446: The form "author, year" in zoology, and "standard abbreviated author name" in botany. Thus in the examples above, the genus Canis would be cited in full as " Canis Linnaeus, 1758" (zoological usage), while Hibiscus , also first established by Linnaeus but in 1753, is simply " Hibiscus L." (botanical usage). Each genus should have a designated type , although in practice there is a backlog of older names without one. In zoology, this

3956-737: The generic name (or its abbreviated form) still forms the leading portion of the scientific name, for example, Canis lupus lupus for the Eurasian wolf subspecies, or as a botanical example, Hibiscus arnottianus ssp. immaculatus . Also, as visible in the above examples, the Latinised portions of the scientific names of genera and their included species (and infraspecies, where applicable) are, by convention, written in italics . The scientific names of virus species are descriptive, not binomial in form, and may or may not incorporate an indication of their containing genus; for example,

4042-432: The idea that a newly defined genus should fulfill these three criteria to be descriptively useful: Moreover, genera should be composed of phylogenetic units of the same kind as other (analogous) genera. The term "genus" comes from Latin genus , a noun form cognate with gignere ('to bear; to give birth to'). The Swedish taxonomist Carl Linnaeus popularized its use in his 1753 Species Plantarum , but

4128-419: The immense bulk of the animal, many bones throughout the skeleton were hollowed, reducing its weight without significant loss of strength. Tyrannosaurus is the type genus of the superfamily Tyrannosauroidea , the family Tyrannosauridae , and the subfamily Tyrannosaurinae; in other words it is the standard by which paleontologists decide whether to include other species in the same group. Other members of

Lost in the dark, he is chased down by a Tyrannosaurus and eaten. The other three agents, unaware of his death, proceed with the mission. After the events of the previous game, unsafe research into time-distorting Third Energy has resulted in an entire research base, military institution, and fictional metropolis of Edward City to be transported to another time; along with all of its inhabitants. Secret Operations Raid Team operative Regina returns as one of

4300-400: The largest Tyrannosaurus skull yet discovered (from a specimen named MOR 008), measuring 5 feet (152 cm) long. Subsequent comparisons indicated that the longest head was 136.5 centimetres (53.7 in) (from specimen LACM 23844) and the widest head was 90.2 centimetres (35.5 in) (from Sue). Two isolated fossilized footprints have been tentatively assigned to T. rex . The first

4386-633: The largest component, with 23,236 ± 5,379 accepted genus names, of which 20,845 ± 4,494 are angiosperms (superclass Angiospermae). By comparison, the 2018 annual edition of the Catalogue of Life (estimated >90% complete, for extant species in the main) contains currently 175,363 "accepted" genus names for 1,744,204 living and 59,284 extinct species, also including genus names only (no species) for some groups. The number of species in genera varies considerably among taxonomic groups. For instance, among (non-avian) reptiles , which have about 1180 genera,

4472-831: The last non- avian dinosaurs to exist before the Cretaceous–Paleogene extinction event . Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, the forelimbs of Tyrannosaurus were short but unusually powerful for their size, and they had two clawed digits. The most complete specimen measures 12.3–12.4 m (40–41 ft) in length, but according to most modern estimates, Tyrannosaurus could have exceeded sizes of 13 m (43 ft) in length, 3.7–4 m (12–13 ft) in hip height, and 8.8 t (8.7 long tons; 9.7 short tons) in mass. Although some other theropods might have rivaled or exceeded Tyrannosaurus in size , it

4558-488: The lower jaw, except at the rear. The largest found so far is estimated to have been 30.5 cm (12.0 in) long including the root when the animal was alive, making it the largest tooth of any carnivorous dinosaur yet found. The lower jaw was robust. Its front dentary bone bore thirteen teeth. Behind the tooth row, the lower jaw became notably taller. The upper and lower jaws of Tyrannosaurus , like those of many dinosaurs, possessed numerous foramina , or small holes in

Dylan Morton, the rescue team leader, is the second playable character. Despite Dylan and Regina initially going their separate ways, they end up joining forces to find a way back to the present. The player switches between controlling Regina and Dylan at specific points during

However, some insect genera such as the bee genera Lasioglossum and Andrena have over 1000 species each. The largest flowering plant genus, Astragalus , contains over 3,000 species. Which species are assigned to a genus

4816-428: The name could not be used for both. Johann Friedrich Blumenbach published the replacement name Ornithorhynchus in 1800. However, a genus in one kingdom is allowed to bear a scientific name that is in use as a generic name (or the name of a taxon in another rank) in a kingdom that is governed by a different nomenclature code. Names with the same form but applying to different taxa are called "homonyms". Although this

Henry Fairfield Osborn recognized the similarity between Manospondylus gigas and T. rex as early as 1917, by which time the second vertebra had been lost. Owing to the fragmentary nature of the Manospondylus vertebrae, Osborn did not synonymize

5074-548: The only specimens of Tyrannosaurus , as the Great Depression and wars kept many paleontologists out of the field. Beginning in the 1960s, there was renewed interest in Tyrannosaurus , resulting in the recovery of 42 skeletons (5–80% complete by bone count) from Western North America. In 1967, Dr. William MacMannis located and recovered the skeleton named "MOR 008", which is 15% complete by bone count and has

The D -shaped cross-section, reinforcing ridges and backwards curve reduced the risk that the teeth would snap when Tyrannosaurus bit and pulled. The remaining teeth were robust, like "lethal bananas" rather than daggers, more widely spaced and also had reinforcing ridges. Those in the upper jaw, twelve per side in mature individuals, were larger than their counterparts of

5418-588: The rock off the bones. The bones were then shipped to New Jersey where the mount was constructed, then shipped back to Chicago for the final assembly. The mounted skeleton opened to the public on May 17, 2000, in the Field Museum of Natural History. A study of this specimen's fossilized bones showed that Sue reached full size at age 19 and died at the age of 28, the longest estimated life of any tyrannosaur known. Another Tyrannosaurus , nicknamed Stan (BHI 3033), in honor of amateur paleontologist Stan Sacrison,

5504-532: The second skeleton T. rex in 1905. The generic name is derived from the Greek words τύραννος ( tyrannos , meaning "tyrant") and σαῦρος ( sauros , meaning "lizard"). Osborn used the Latin word rex , meaning "king", for the specific name. The full binomial therefore translates to "tyrant lizard the king" or "King Tyrant Lizard", emphasizing the animal's size and presumed dominance over other species of

5590-497: The specific name particular to the wolf. A botanical example would be Hibiscus arnottianus , a particular species of the genus Hibiscus native to Hawaii. The specific name is written in lower-case and may be followed by subspecies names in zoology or a variety of infraspecific names in botany . When the generic name is already known from context, it may be shortened to its initial letter, for example, C. lupus in place of Canis lupus . Where species are further subdivided,

5676-412: The standard format for a species name comprises the generic name, indicating the genus to which the species belongs, followed by the specific epithet, which (within that genus) is unique to the species. For example, the gray wolf 's scientific name is Canis lupus , with Canis ( Latin for 'dog') being the generic name shared by the wolf's close relatives and lupus (Latin for 'wolf') being

5848-588: The summer of 2000, crews organized by Jack Horner discovered five Tyrannosaurus skeletons near the Fort Peck Reservoir . In 2001, a 50% complete skeleton of a juvenile Tyrannosaurus was discovered in the Hell Creek Formation by a crew from the Burpee Museum of Natural History . Dubbed Jane (BMRP 2002.4.1), the find was thought to be the first known skeleton of a pygmy tyrannosaurid, Nanotyrannus , but subsequent research revealed that it

5934-403: The taxon is termed a synonym ; some authors also include unavailable names in lists of synonyms as well as available names, such as misspellings, names previously published without fulfilling all of the requirements of the relevant nomenclatural code, and rejected or suppressed names. A particular genus name may have zero to many synonyms, the latter case generally if the genus has been known for

6020-527: The time. Osborn named the other specimen Dynamosaurus imperiosus in a paper in 1905. In 1906, Osborn recognized that the two skeletons were from the same species and selected Tyrannosaurus as the preferred name. In 1941, the T. rex type specimen was sold to the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania, for $ 7,000. The original Dynamosaurus material now resides in

6106-422: The transition point between the deep tail base and the middle tail that was stiffened by a rather long front articulation processes. The underside of the trunk was covered by eighteen or nineteen pairs of segmented belly ribs. The shoulder girdle was longer than the entire forelimb. The shoulder blade had a narrow shaft but was exceptionally expanded at its upper end. It connected via a long forward protrusion to

6192-429: The two genera, instead considering the older genus indeterminate. In June 2000, the Black Hills Institute found around 10% of a Tyrannosaurus skeleton ( BHI 6248) at a site that might have been the original M. gigas locality. Barnum Brown , assistant curator of the American Museum of Natural History , found the first partial skeleton of T. rex in eastern Wyoming in 1900. Brown found another partial skeleton in

6278-587: The tyrannosaurine subfamily include the North American Daspletosaurus and the Asian Tarbosaurus , both of which have occasionally been synonymized with Tyrannosaurus . Tyrannosaurids were once commonly thought to be descendants of earlier large theropods such as megalosaurs and carnosaurs , although more recently they were reclassified with the generally smaller coelurosaurs . The earliest tyrannosaur group were

6364-466: The upper jaw was U-shaped (most non-tyrannosauroid carnivores had V-shaped upper jaws), which increased the amount of tissue and bone a tyrannosaur could rip out with one bite, although it also increased the stresses on the front teeth. The teeth of T. rex displayed marked heterodonty (differences in shape). The premaxillary teeth, four per side at the front of the upper jaw, were closely packed, D -shaped in cross-section, had reinforcing ridges on

6450-576: The values quoted are the mean of "accepted" names alone (all "uncertain" names treated as unaccepted) and "accepted + uncertain" names (all "uncertain" names treated as accepted), with the associated range of uncertainty indicating these two extremes. Within Animalia, the largest phylum is Arthropoda , with 151,697 ± 33,160 accepted genus names, of which 114,387 ± 27,654 are insects (class Insecta). Within Plantae, Tracheophyta (vascular plants) make up

6536-429: The virus species " Salmonid herpesvirus 1 ", " Salmonid herpesvirus 2 " and " Salmonid herpesvirus 3 " are all within the genus Salmonivirus ; however, the genus to which the species with the formal names " Everglades virus " and " Ross River virus " are assigned is Alphavirus . As with scientific names at other ranks, in all groups other than viruses, names of genera may be cited with their authorities, typically in

6622-481: Was 3.66–3.96 m (12.0–13.0 ft) tall at the hips, and according to the most recent studies, using a variety of techniques, maximum body masses have been estimated approximately 8.4–8.46 t (8.27–8.33 long tons; 9.26–9.33 short tons). A specimen nicknamed Scotty (RSM P2523.8), located at the Royal Saskatchewan Museum , is reported to measure 13 m (43 ft) in length. Using

6708-483: Was circulating news that Capcom had begun development on Dino Crisis 4 with the intention of announcing the sequel at the Tokyo Game Show of that year. Tao Weishi, the producer of Monster Hunter Online , was interested in working with Capcom on a revival of the Dino Crisis series. Bocanegra stated: "It would certainly be nice to get a Dino Crisis revival. And Capcom could potentially start by remastering

6794-558: Was discovered at Philmont Scout Ranch , New Mexico, in 1983 by American geologist Charles Pillmore. Originally thought to belong to a hadrosaurid , examination of the footprint revealed a large 'heel' unknown in ornithopod dinosaur tracks, and traces of what may have been a hallux , the dewclaw-like fourth digit of the tyrannosaur foot. The footprint was published as the ichnogenus Tyrannosauripus pillmorei in 1994, by Martin Lockley and Adrian Hunt. Lockley and Hunt suggested that it

6880-480: Was estimated to have a hip height of 1.56 to 2.06 m (5.1 to 6.8 ft). A follow-up paper appeared in 2017, increasing the speed estimations by 50–80%. T. rex was one of the largest land carnivores of all time. One of its largest and the most complete specimens, nicknamed Sue (FMNH PR2081), is located at the Field Museum of Natural History in Chicago. Sue measured 12.3–12.4 m (40–41 ft) long,

6966-504: Was found after an analysis conducted by Li and colleagues in 2009. Guanlong [REDACTED] Proceratosaurus Dilong [REDACTED] Eotyrannus Xiongguanlong [REDACTED] Appalachiosaurus Tyrannosauridae [REDACTED] Many phylogenetic analyses have found Tarbosaurus bataar to be the sister taxon of T. rex . The discovery of the tyrannosaurid Lythronax further indicates that Tarbosaurus and Tyrannosaurus are closely related, forming

7052-408: Was little evidence of size-based sexual dimorphism in T. rex . The largest known T. rex skulls measure up to 1.54 m (5.1 ft) in length. Large fenestrae (openings) in the skull reduced weight, as in all carnivorous theropods. In other respects Tyrannosaurus 's skull was significantly different from those of large non- tyrannosaurid theropods. It was extremely wide at the rear but had

7138-463: Was longer and wider than the first, whereas normally in theropods the opposite is true. The forelimbs had only two clawed fingers, along with an additional splint-like small third metacarpal representing the remnant of a third digit. The pelvis was a large structure. Its upper bone, the ilium , was both very long and high, providing an extensive attachment area for hindlimb muscles. The front pubic bone ended in an enormous pubic boot, longer than

7224-409: Was recovered from the Hell Creek Formation in 1992. Stan is the second most complete skeleton found, with 199 bones recovered representing 70% of the total. This tyrannosaur also had many bone pathologies, including broken and healed ribs, a broken (and healed) neck, and a substantial hole in the back of its head, about the size of a Tyrannosaurus tooth. In 1998, 20-year-old Bucky Derflinger noticed

7310-461: Was released by Yujin in the Namco × Capcom series. Tyrannosaurus Tyrannosaurus ( / t ɪ ˌ r æ n ə ˈ s ɔː r ə s , t aɪ -/ ) is a genus of large theropod dinosaur . The type species Tyrannosaurus rex ( rex meaning 'king' in Latin ), often shortened to T. rex or colloquially T-Rex , is one of the best represented theropods. It lived throughout what

7396-400: Was very likely the track was made by a T. rex , which would make it the first known footprint from this species. The track was made in what was once a vegetated wetland mudflat. It measures 83 centimeters (33 in) long by 71 centimeters (28 in) wide. A second footprint that may have been made by a Tyrannosaurus was first reported in 2007 by British paleontologist Phil Manning, from
