20-465: Elevation Science runs a six-week field expedition each summer in southern Montana and northern Wyoming to collect fossils of dinosaurs and other Mesozoic vertebrates. Field programs generally run from late June through mid-August. These field expeditions are open to sign-ups for individuals to learn about the geology, paleontology, and natural history of the region while aiding Elevation Science paleontologists in collecting fossils for research. For students,

40-427: A taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow consistent naming schemes . Orders of plants , fungi , and algae use the suffix -ales (e.g. Dictyotales ). Orders of birds and fishes use

60-407: Is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist , as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that

80-659: The Prodromus Systematis Naturalis Regni Vegetabilis of Augustin Pyramus de Candolle and the Genera Plantarum of Bentham & Hooker, it indicated taxa that are now given the rank of family (see ordo naturalis , ' natural order '). In French botanical publications, from Michel Adanson 's Familles naturelles des plantes (1763) and until the end of the 19th century, the word famille (plural: familles )

100-587: The Hell Creek Formation . Torotix T. clemensi A possible pelecaniform Order (biology) Order ( Latin : ordo ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy . It is classified between family and class . In biological classification , the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes . An immediately higher rank, superorder ,

120-669: The Lance, roughly corresponding to the thinner equivalent formations such as the Hell Creek Formation, the base of which has been estimated at 66.8 million years old. The formation is described by W.G. Pierce as thick-bedded, buff-colored sandstone, and drab to green shale. It is Upper Cretaceous in age. The formation varies in thickness from about 90 m (300 ft.) in North Dakota , to almost 600 m (2,000 ft.) in parts of Wyoming. The Lance Formation

140-696: The Latin suffix -iformes meaning 'having the form of' (e.g. Passeriformes ), but orders of mammals and invertebrates are not so consistent (e.g. Artiodactyla , Actiniaria , Primates ). For some clades covered by the International Code of Zoological Nomenclature , several additional classifications are sometimes used, although not all of these are officially recognized. In their 1997 classification of mammals , McKenna and Bell used two extra levels between superorder and order: grandorder and mirorder . Michael Novacek (1986) inserted them at

160-472: The ending -anae that was initiated by Armen Takhtajan 's publications from 1966 onwards. The order as a distinct rank of biological classification having its own distinctive name (and not just called a higher genus ( genus summum )) was first introduced by the German botanist Augustus Quirinus Rivinus in his classification of plants that appeared in a series of treatises in the 1690s. Carl Linnaeus

180-910: The field of zoology , the Linnaean orders were used more consistently. That is, the orders in the zoology part of the Systema Naturae refer to natural groups. Some of his ordinal names are still in use, e.g. Lepidoptera (moths and butterflies) and Diptera (flies, mosquitoes, midges, and gnats). In virology , the International Committee on Taxonomy of Viruses 's virus classification includes fifteen taxomomic ranks to be applied for viruses , viroids and satellite nucleic acids : realm , subrealm , kingdom , subkingdom, phylum , subphylum , class, subclass, order, suborder, family, subfamily , genus, subgenus , and species. There are currently fourteen viral orders, each ending in

200-1297: The formation are freshwater animals, and some are exclusively freshwater forms (for instance, frogs and salamanders). However, marine fossils are also found in the formation, suggesting that the sea was nearby. The bird fauna is mainly composed of orders still existing today. Apatornis A. retusus Reclassified as Palintropus retusus Ceramornis C. major A possible charadriiform bird Cimolopteryx C. petra Reclassified as Lamarqueavis minima C. rara A charadriiform C. retusa Reclassified as Palintropus retusus C. minima Reclassified as Lamarqueavis minima "Cimolopteryx" " C." maxima A charadriiform bird, not necessarily closely related to Cimolopteryx . Graculavus G. augustus A possible charadriiform Lamarqueavis L. minima A charadriiform L. petra A charadriiform Lonchodytes L. estesi A possible procellariiform "Lonchodytes" "L." pterygius A possible charadriiform " Palaeotringa " "P." vetus A bird similar to gruids , idiornithids and presbyornithids . Palintropus P. retusus A basal ornithuromorph belonging to Ambiortiformes . Potamornis P. skutchi A hesperornithiform possibly also present in

220-648: The fossil discoveries that have been made within their region. Elevation Science dig sites are largely within the Lance and Morrison formations, though they have also spanned through the Cloverly , Fort Union , and Willwood formations. Nearly all Elevation Science localities lie within Carbon County, MT. Among Elevation Science excavation sites is the Mother's Day Quarry which the team has been excavating since

240-703: The lower part of the Scollard Formation of Alberta. The Lance Formation occurs above the Baculites clinolobatus ammonite marine zone in Wyoming, the top of which has been dated to about 69 million years ago, and extends to the K-Pg boundary, 66 million years ago. However, the characteristic land vertebrate fauna of the Lancian age (which take its name from this formation) is only found in the upper strata of

260-545: The program is available as a for-credit field paleontology course through Montana State University, Billings. From 2017 to 2019, Elevation Science also offered a dinosaur-themed summer camp program entitled Dinosaur Treasures in Our Backyard for children throughout rural Carbon County, Montana and in Cody, Wyoming. The program features several lessons and hands-on activities to teach children about dinosaurs, paleontology, and

280-420: The same position. Michael Benton (2005) inserted them between superorder and magnorder instead. This position was adopted by Systema Naturae 2000 and others. In botany , the ranks of subclass and suborder are secondary ranks pre-defined as respectively above and below the rank of order. Any number of further ranks can be used as long as they are clearly defined. The superorder rank is commonly used, with

300-447: The summer of 2017. Elevation Science has excavated a wide variety of dinosaur genera including Diplodocus , Tyrannosaurus , Allosaurus , Triceratops , Leptoceratops , Suuwassea , Edmontosaurus , Ankylosaur , and many others. Their finds have included many crocodilian, turtle, and plant fossils as well. Lance Formation The Lance (Creek) Formation is a division of Late Cretaceous (dating to about 69–66 Ma) rocks in

320-474: The western United States. Named after Lance Creek, Wyoming , the microvertebrate fossils and dinosaurs represent important components of the latest Mesozoic vertebrate faunas. The Lance Formation is Late Maastrichtian in age ( Lancian land mammal age ), and shares much fauna with the Hell Creek Formation of Montana and North Dakota, the Frenchman Formation of southwest Saskatchewan, and

340-578: The word family ( familia ) was assigned to the rank indicated by the French famille , while order ( ordo ) was reserved for a higher rank, for what in the 19th century had often been named a cohors (plural cohortes ). Some of the plant families still retain the names of Linnaean "natural orders" or even the names of pre-Linnaean natural groups recognized by Linnaeus as orders in his natural classification (e.g. Palmae or Labiatae ). Such names are known as descriptive family names. In

360-620: Was laid down by streams, on a coastal plain along the edge of the Western Interior Seaway . The climate was subtropical; there was no cold season and probably ample precipitation . At least tens of thousands of Late Cretaceous vertebrate remains have been recovered from the Lance Formation. Fossils ranging from microscopic elements to extensive bonebeds , with nearly complete, sometimes articulated dinosaur skeletons, have been found. Most other animals known from

380-551: Was the first to apply it consistently to the division of all three kingdoms of nature (then minerals , plants , and animals ) in his Systema Naturae (1735, 1st. Ed.). For plants, Linnaeus' orders in the Systema Naturae and the Species Plantarum were strictly artificial, introduced to subdivide the artificial classes into more comprehensible smaller groups. When the word ordo was first consistently used for natural units of plants, in 19th-century works such as

400-561: Was used as a French equivalent for this Latin ordo . This equivalence was explicitly stated in the Alphonse Pyramus de Candolle 's Lois de la nomenclature botanique (1868), the precursor of the currently used International Code of Nomenclature for algae, fungi, and plants . In the first international Rules of botanical nomenclature from the International Botanical Congress of 1905,
