Velociraptorinae
Velociraptorinae is a subfamily of the theropod group Dromaeosauridae. The earliest velociraptorines are probably ''Nuthetes'' from the United Kingdom, and possibly ''Deinonychus'' from North America. However, several indeterminate velociraptorines have also been discovered, dating to the Kimmeridgian stage, in the Late Jurassic Period. These fossils were discovered in the Langenberg quarry, Oker near Goslar, Germany.van der Lubbe, T., Richter, U. and Knotschke, N. (2009).Velociraptorine dromaeosaurid teeth from the Kimmeridgian (Late Jurassic) of Germany" ''Acta Palaeontologica Polonica'', 54(3): 401-408. Description While most velociraptorines were generally small animals, at least one species may have achieved gigantic sizes comparable to those found among the dromaeosaurines. So far, this unnamed giant velociraptorine is known only from isolated teeth found on the Isle of Wight, England. The teeth belong to an animal the size of dromaeosaurines of the genus ''Utahraptor'', bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adasaurus
''Adasaurus'' ( ; meaning "Ada lizard") is a genus of dromaeosaurid dinosaur that lived in Asia during the Late Cretaceous period about 70 million years ago. The genus is known from two partial specimens found in the Nemegt Formation of Mongolia that were partially described in 1983 by the paleontologist Rinchen Barsbold. ''Adasaurus'' was a large dromaeosaurid that was about long weighing . Unlike other dromaeosaurids, ''Adasaurus'' developed a rather small and blunt sickle claw that likely had a reduced use, and a recurved lacrimal bone; this latter trait is also shared with ''Austroraptor''. Though reduced, the sickle claw retained the characteristic rounded articulation of most dromaeosaurids. ''Adasaurus'' was originally regarded as a dromaeosaurine by Barsbold, a group that includes robust dromaeosaurs with deep jaws. Revisions made to the specimens have showed that this dromaeosaurid belongs to the Velociraptorinae which is composed of more lightly built animals like ''V ...

Velociraptor Mongoliensis
''Velociraptor'' (; ) is a genus of small dromaeosaurid dinosaur that lived in Asia during the Late Cretaceous epoch, about 75 million to 71 million years ago. Two species are currently recognized, although others have been assigned in the past. The type species is ''V. mongoliensis''; fossils of this species have been discovered in the Djadochta Formation, Mongolia. A second species, ''V. osmolskae'', was named in 2008 for skull material from the Bayan Mandahu Formation, China. Smaller than other dromaeosaurids like ''Deinonychus'' and ''Achillobator'', ''Velociraptor'' was about long with a body mass between . It nevertheless shared many of the same anatomical features. It was a bipedal, feathered carnivore with a long tail and an enlarged sickle-shaped claw on each hindfoot, which is thought to have been used to tackle and restrain prey. ''Velociraptor'' can be distinguished from other dromaeosaurids by its long and low skull, with an upturned snout. ''Velociraptor'' (com ...

Dromaeosauridae
Dromaeosauridae () is a family of feathered theropod dinosaurs. They were generally small to medium-sized feathered carnivores that flourished in the Cretaceous Period. The name Dromaeosauridae means 'running lizards', from Greek ('), meaning 'runner', and ('), meaning 'lizard'. In informal usage, they are often called raptors (after ''Velociraptor''), a term popularized by the film '' Jurassic Park''; a few types include the term "raptor" directly in their name and have come to emphasize their bird-like appearance and speculated bird-like behavior. Dromaeosaurid fossils have been found across the globe in North America, Europe, Africa, Asia, South America and Antarctica, with some fossils giving credence to the possibility that they inhabited Australia as well. They first appeared in the mid-Jurassic Period (late Bathonian stage, about 167 million years ago) and survived until the end of the Cretaceous (Maastrichtian stage, 66 ma), existing until the Cretaceous–Paleogene ex ...

Dineobellator
''Dineobellator'' (meaning Diné warrior, pronounced ) is a genus of dromaeosaurid theropod dinosaur that lived in North America during the Late Cretaceous period 68 million years ago. The remains have been found in the Maastrichtian stage of the Naashoibito Member at the Ojo Alamo Formation, New Mexico. Material was copied from this source, which is available under Creative Commons Attribution 4.0 International License Discovery and naming The holotype remains are designated SMP VP-2430 and were first recovered in 2008 from the Ojo Alamo Formation by Robert M. Sullivan, Steven E. Jasinski and James Nikas. Sullivan and Jasinski collected additional material in 2009. In 2011, the find was reported in the scientific literature. Further excavations were performed by Jasinski in 2015 and 2016. The remains were realized as belonging to a new taxon, which was only named and described in 2020, by Jasinski, Sullivan and Peter Dodson. It was given the species name ''Dineobellator noto ...

Deinonychus
''Deinonychus'' ( ; ) is a genus of dromaeosaurid theropod dinosaur with one described species, ''Deinonychus antirrhopus''. This species, which could grow up to long, lived during the early Cretaceous Period, about 115–108 million years ago (from the mid-Aptian to early Albian stages). Fossils have been recovered from the U.S. states of Montana, Utah, Wyoming, and Oklahoma, in rocks of the Cloverly Formation, Cedar Mountain Formation and Antlers Formation, though teeth that may belong to ''Deinonychus'' have been found much farther east in Maryland. Paleontologist John Ostrom's study of ''Deinonychus'' in the late 1960s revolutionized the way scientists thought about dinosaurs, leading to the " dinosaur renaissance" and igniting the debate on whether dinosaurs were warm-blooded or cold-blooded. Before this, the popular conception of dinosaurs had been one of plodding, reptilian giants. Ostrom noted the small body, sleek, horizontal posture, ratite-like spine, and esp ...

Dromaeosaurinae
Dromaeosaurinae is a subfamily of the theropod group Dromaeosauridae. The earliest dromaeosaurine is ''Utahraptor'', dating back to the Early Cretaceous period in North America, however, some isolated teeth seems to represent an indeterminate species of dromaeosaurine, coming from the Late Jurassic period in Africa. If true, this will push their range to the Jurassic period, instead of the Cretaceous, as in most dromaeosaurs. Most dromaeosaurs are small carnivores, however, dromaeosaurines are represented by some of the largest species (''Achillobator'', ''Dakotaraptor'', ''Utahraptor''). So far, ''Dakotaraptor'' is the only dromaeosaurine with evidence of quill knobs, indicating a plumage; based on this, other members likely had them. Paleobiogeography Most dromaeosaurines lived in what is now Asia, North America and possibly Denmark during the Cretaceous period, from the Berriasian to the Maastrichtian stages. However, isolated teeth that may belong to African dromaeosaurines h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utahraptor
''Utahraptor'' (meaning "Utah's thief") is a genus of large dromaeosaurid dinosaur that lived in North America during the Early Cretaceous period. It was a heavy-built, ground-dwelling, bipedal carnivore. It contains a single species, ''Utahraptor ostrommaysi'', which is one of the largest-known members of the family Dromaeosauridae, measuring long and weighing . Discovery and naming The first specimens of ''Utahraptor'' were found in 1975 by Jim Jensen in the Dalton Wells Quarry in east-central Utah, near the town of Moab, but did not receive much attention. After a find of a large foot-claw by Carl Limone in October 1991, James Kirkland, Robert Gaston, and Donald Burge uncovered further remains of ''Utahraptor'' in 1991 in the Gaston Quarry in Grand County, Utah, within the Yellow Cat and Poison Strip members of the Cedar Mountain Formation. The holotype of ''Utahraptor'', CEUM 184v.86 consists of a second pedal ungual, with potentially assigned elements from other specim ...

Acheroraptor
''Acheroraptor'' is an extinct genus of dromaeosaurid theropod dinosaur known from the latest Maastrichtian Hell Creek Formation of Montana, United States. It contains a single species, ''Acheroraptor temertyorum''. ''A. temertyorum'' is one of the two geologically youngest known species of dromaeosaurids, the other being ''Dakotaraptor'', which is also known from Hell Creek. A basal cousin of ''Velociraptor'', ''Acheroraptor'' is known from upper and lower jaw material. Discovery and naming ''Acheroraptor'' was first described and named by David C. Evans, Derek W. Larson and Philip J. Currie in 2013 and the type species is ''Acheroraptor temertyorum''. The generic name is derived from the Greek Ἀχέρων, ''Acheron'', "underworld", in reference to the provenance from the Hell Creek Formation, and the Latin ''raptor'', "thief". The specific name honours James and Louise Temerty, the chairman of Northland Power and the ROM Board of Governors and his wife, who have support ...
