Coelophysoidea
Coelophysoidea is an extinct clade of theropod dinosaurs common during the Late Triassic and Early Jurassic periods. They were widespread geographically, probably living on all continents. Coelophysoids were all slender, carnivorous forms with a superficial similarity to the coelurosaurs, with which they were formerly classified, and some species had delicate cranial crests. Sizes range from about 1 to 6 m in length. It is unknown what kind of external covering coelophysoids had, and various artists have portrayed them as either scaly or feathered. Some species may have lived in packs, as inferred from sites where numerous individuals have been found together. Examples of coelophysoids include ''Coelophysis'', ''Procompsognathus'' and '' Liliensternus''. Most dinosaurs formerly referred to as being in the dubious taxon "Podokesauridae" are now classified as coelophysoids. The family Coelophysidae, which is contained within Coelophysoidea, flourished in the Late Triassic and Ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megapnosaurus
''Megapnosaurus'' (meaning "big dead lizard", from Greek μέγα = "big", ἄπνοος = "not breathing", "dead", σαῦρος = "lizard") is an extinct genus of coelophysid theropod dinosaur that lived approximately 188 million years ago during the early part of the Jurassic Period in what is now Africa. The species was a small to medium-sized, lightly built, ground-dwelling, bipedal carnivore, that could grow up to long and weigh up to . It was originally given the genus name ''Syntarsus'', but that name was later determined to be preoccupied by a beetle. The species was subsequently given a new genus name, ''Megapnosaurus'', by Ivie, Ślipiński & Węgrzynowicz in 2001. Some studies have classified it as a species within the genus ''Coelophysis,'' but this interpretation has been challenged by more subsequent studies and the genus ''Megapnosaurus'' is now considered valid. Discovery and history The first fossils of ''Megapnosaurus'' were found in 1963 by a group of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coelophysis? Kayentakatae
''Coelophysis''? ''kayentakatae'' is an extinct species of neotheropod dinosaur that lived approximately 200–196 million years ago during the early part of the Jurassic Period in what is now the southwestern United States. It was originally named ''Syntarsus kayentakatae'', but the genus ''Syntarsus'' was found to be preoccupied by a Colydiine beetle, so it was moved to the genus ''Megapnosaurus'', and then to ''Coelophysis''. A 2022 reassessment suggests that this species may require a new genus name. Discovery The holotype of "S." ''kayentakatae'' (MNA V2623) was recovered in the Silty Facies Member of the Kayenta Formation in Arizona. This material was collected in 1977 from carbonaceous sandstone deposited during the Sinemurian and Pliensbachian stages of the Jurassic period.Padian, K (1997) Glen Canyon Group In: Encyclopedia of Dinosaurs, edited by Currie, P.

Gojirasaurus
''Gojirasaurus'' (meaning "Godzilla lizard") is a genus of " coelophysoid" theropod dinosaur from the Late Triassic of New Mexico. It is named after the giant monster movie character , and contains a single species, ''Gojirasaurus quayi''. Discovery ''Gojirasaurus quayi'' was described and named by Kenneth Carpenter in 1997 based on a partial skeleton, the holotype specimen UCM 47221, from Quay County, New Mexico. The holotype is an assortment of various postcranial bones, including a right scapula, right pubis, left tibia, left metatarsal V, four vertebral centra, a neural arch, and fragments of ribs and gastralia. In addition, a single large serrated tooth is associated with the postcranial material. The holotype is housed in the collections of the University of Colorado Museum of Natural History, in Boulder, Colorado. The specimen hails from purplish-grey mudstones of the Bull Canyon Formation (sometimes called the Cooper Canyon Formation), a major fossiliferou ...

Theropod
Theropoda (; from ancient Greek , (''therion'') "wild beast"; , (''pous, podos'') "foot"">wiktionary:ποδός"> (''pous, podos'') "foot" is one of the three major groups (clades) of dinosaurs, alongside Ornithischia and Sauropodomorpha. Theropods, both extant and extinct, are characterized by hollow bones and three toes and claws on each limb. They are generally classed as a group of saurischian dinosaurs, placing them closer to sauropodomorphs than to ornithischians. They were ancestrally carnivorous, although a number of theropod groups evolved to become herbivores and omnivores. Members of the subgroup Coelurosauria and possibly some other or all theropods were covered in feathers. In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are currently represented by about 11,000 living species, making theropods the only group of dinosaurs alive today. Theropods first appeared during the Carnian age of the late Triassic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liliensternus
''Liliensternus'' is an extinct genus of basal neotheropod dinosaur that lived approximately 210 million years ago during the latter part of the Triassic Period in what is now Germany. ''Liliensternus'' was a bipedal, ground-dwelling carnivore, that could grow up to long; however, this size estimate is based on specimens now believed to be subadults, and possible fragmentary remains indicate an adult length of 7 to 9 meters.Eudald Mujal, Hans-Dieter Sues, Raphael Moreno, Joep Schaeffer, Gabriela Sobral, Sanjukta Chakravorti, Stephan N.F.

Coelophysis
''Coelophysis'' ( Traditional English pronunciation of Latin, traditionally; or , as heard more commonly in recent decades) is a genus of coelophysid Theropoda, theropod dinosaur that lived Approximation, approximately 215 to 201.4 million years ago during the Late Triassic Period (geology), period from the middle Norian to Rhaetian age in what is now the southwestern United States. ''Megapnosaurus'' was once considered to be a species within this genus, but this interpretation has been challenged and the genus ''Megapnosaurus'' is now considered valid. ''Coelophysis'' was a small, slenderly built, ground-dwelling, bipedal carnivore that could grow up to long. It is one of the earliest known dinosaur genera. Scattered material representing similar animals has been found worldwide in some Late Triassic and Early Jurassic formations. The type species ''C. bauri'', originally given to the genus ''Coelurus'' by Edward Drinker Cope in 1887, was described by the latter in 1889. T ...

Dracoraptor
''Dracoraptor'' (meaning "dragon thief") is a genus of coelophysoid dinosaur that lived during the Hettangian stage of the Early Jurassic Period of what is now Wales dated at 201.3 ± 0.2 million years old. The fossil was first discovered in 2014 by Rob and Nick Hanigan and Sam Davies at the Blue Lias Formation on the South Wales coast. The genus name ''Dracoraptor'' is from Draco referring to the Welsh dragon and raptor, meaning robber, a commonly employed suffix for theropod dinosaurs with the type species being ''Dracoraptor hanigani''. It is the oldest known Jurassic dinosaur and is the first dinosaur skeleton from the Jurassic of Wales. Discovery and naming The first ''Dracoraptor'' fossils were discovered in 2014 near the Welsh town of Penarth. In March 2014, brothers and amateur palaeontologists Nick and Rob Hanigan, while searching for ichthyosaur remains at Lavernock Point, a large cape south of Cardiff, found stone plates containing dinosaur fossils which had fall ...

Podokesaurus
''Podokesaurus'' is a genus of coelophysoid dinosaur that lived in what is now the eastern United States during the Early Jurassic Period. The first fossil was discovered by the geologist Mignon Talbot near Mount Holyoke, Massachusetts, in 1910. The specimen was fragmentary, preserving much of the body, limbs, and tail. In 1911, Talbot described and named the new genus and species ''Podokesaurus holyokensis'' based on it. The full name can be translated as "swift-footed lizard of Holyoke". This discovery made Talbot the first woman to find and describe a non-bird dinosaur. The holotype fossil was recognized as significant and was studied by other researchers, but was lost when the building it was kept in burned down in 1917; no unequivocal ''Podokesaurus'' specimens have since been discovered. It was made state dinosaur of Massachusetts in 2022. Estimated to have been about in length and in weight, ''Podokesaurus'' was lightly constructed with hollow bones, and would have ...

Lophostropheus
''Lophostropheus'' (pronounced: "LOAF-oh-STRO-fee-us") is an extinct genus of coelophysoid theropod dinosaur that lived approximately 205.6 to 196.5 million years ago during the boundary between the Late Triassic Period and the Early Jurassic Period, in what is now Normandy, France. ''Lophostropheus'' is one of the few dinosaurs that may have survived the Triassic–Jurassic extinction event. ''Lophostropheus'' was a small to medium-sized, moderately-built, ground-dwelling, bipedal carnivore, that could grow up to long. Over the years it had been incorrectly classified as '' Halticosaurus'' and ''Liliensternus'', but was later recognized as a new genus and was reassigned to ''Lophostropheus'' in 2007. Etymology ''Lophostropheus'' was described and named by Argentine paleontologist Martin Ezcurra (Museo Argentino de Ciencias Naturales) and French paleontologist Gilles Cuny of the Université Pierre et Marie Curie in 2007, and the type species is ''Lophostropheus airelensis''. ...

Lepidus Praecisio
''Lepidus'' is a genus of extinct theropod from the Upper Triassic of the United States. It lived in the Otis Chalk localities of the Dockum Group in Texas, from 231 to 223 million years ago. Discovery The locality from which ''Lepidus'' is known was discovered in the middle of February 1941 by the Works Progress Administration paleontology team in Texas. The precise geographic locality is precisely unknown, but at the least it is known that the locality is eight miles southeast of the city of Big Spring in Howard County, Texas. Using Google Earth and USGS cartographic maps, the describing authors were able to deduce the fossils were located in the vicinity of Signal Peak. The locality is situated in the Colorado City Formation, which is constrained to about 231-223 Ma in the Carnian to Norian stages of the Upper Triassic. It was first described in 2015 by Nesbitt & Ezcurra, who decided it warranted a new taxon, which they named ''Lepidus praecisio''. The generic name is ...

Pendraig
''Pendraig'' (meaning "chief dragon" in Middle Welsh) is a genus of coelophysoid theropod dinosaur from South Wales. It contains one species, ''Pendraig milnerae'', named after Angela Milner. The specimen was discovered in the Pant-y-Ffynnon Quarry, Pant-y-Ffynnon quarry. In life it would have measured in length. History The holotype of ''Pendraig'' were found in the Pant-y-Ffynnon Quarry, Pant-y-ffynnon Quarry in Wales in 1952 by Kenneth Kermack, Kenneth Alexander Kermack and Pamela Lamplugh Robinson along with the holotypes of ''Pantydraco'' and ''Terrestrisuchus'', and were subsequently lost in the collections of the Natural History Museum, London. The fossils were originally thought to belong to a "coelurosaur" (in the outdated sense of the word) and even subsequently classified as a species of "''Syntarsus''" (now ''Megapnosaurus'' or ''Coelophysis''). Recently Angela Milner and Susannah Maidment rediscovered the fossils stored with some crocodile bones (likely ''Terrestris ...
