Podokesauridae
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] |
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 ...

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 ...

Late Triassic
The Late Triassic is the third and final epoch (geology), epoch of the Triassic geologic time scale, Period in the geologic time scale, spanning the time between annum, Ma and Ma (million years ago). It is preceded by the Middle Triassic Epoch and followed by the Early Jurassic Epoch. The corresponding series (stratigraphy), series of rock beds is known as the Upper Triassic. The Late Triassic is divided into the Carnian, Norian and Rhaetian Geologic time scale, ages. Many of the first dinosaurs evolved during the Late Triassic, including ''Plateosaurus'', ''Coelophysis'', ''Herrerasaurus'', and ''Eoraptor''. The Triassic–Jurassic extinction event began during this epoch and is one of the five major mass extinction events of the Earth. Etymology The Triassic was named in 1834 by Friedrich August von Namoh, Friedrich von Alberti, after a succession of three distinct rock layers (Greek meaning 'triad') that are widespread in southern Germany: the lower Buntsandstein (colourful ...

Friedrich Von Huene
Baron Friedrich Richard von Hoyningen-Huene (22 March 1875 – 4 April 1969) was a German nobleman paleontologist who described a large number of dinosaurs, more than anyone else in 20th-century Europe. He studied a range of Permo-Carboniferous tetrapods. He worked at the collections of the institute and museum for geology and paleontology at the University of Tübingen. Biography Von Huene was born in Tübingen, Kingdom of Württemberg and came from a noble Baltic German family. He took this Baltic identity to heart and would later call his home on Zeppelinstraße (now Payerstraße) as ''Villa Baltica''. His father Johannes von Hoyningen called Huene was a Lutheran minister who had studied theology at Göttingen, Tübingen and Dorpat. His mother Alexandra Baronesse Stackelberg came from an Estonian noble family. The junior Huene was also brought up with deeply religious beliefs. He grew up in Switzerland as his father taught at Basel. He also visited Latvia as a child and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Procompsognathus
''Procompsognathus'' is an extinct genus of Coelophysidae, coelophysid Theropoda, theropod dinosaur that lived approximately 210 million years ago during the later part of the Triassic Period (geology), Period, in what is now Germany. ''Procompsognathus'' was a small-sized, lightly built, ground-dwelling, bipedal carnivore, that could grow up to long. Discovery and naming The fragmentary and poorly preserved skeleton of ''Procompsognathus'' was found in the Middle Stubensandstein member of the Löwenstein Formation at the ''Weiße Steinbruch'', the quarry of Albert Burrer on the northern slopes of the Baden-Württemberg, Stromberg region near Pfaffenhofen, Baden-Württemberg, Pfaffenhofen in Württemberg, Germany. The discovery was made by Albert Burrer in the spring of 1909 in white sandstone and gray/blue marl sediments that were deposited during the Norian Stage (stratigraphy), stage of the Triassic period. The holotype SMNS 12591, consisted of three blocks of sandstone: on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pterospondylus
''Pterospondylus'' (meaning "winged vertebra") is a dubious genus of theropod dinosaur from the Late Triassic. It was a coelophysid theropod which lived in what is now Germany ( Trossingen Formation). The type species, ''Pterospondylus trielbae'', (derived from "Tri", in reference to the Triassic period, and "Elba", for the Elbe River area), was described by Jaekel in 1913–14 for a single back vertebra found inside the shell of the ''Proganochelys'' turtle.

Segisaurus
''Segisaurus'' (meaning "Tsegi Canyon lizard") is a genus of small coelophysid theropod dinosaur, that measured approximately 1 metre (3.3 feet) in length. The only known specimen was discovered in early Jurassic strata in Tsegi Canyon, Arizona, for which it was named. ''Segisaurus'' is the only dinosaur to have ever been excavated from the area. Description ''Segisaurus'' lived sometime between ~200 and 195 million years ago during the Jurassic period. It was a primitive bipedal theropod roughly around the size of a goose. ''Segisaurus'' was 1 meter (3.3 feet) long, half a meter (1.65 feet) tall and weighed about 4-7 kilograms. It was nimble and Insectivore, insectivorous, although it may have scavenged meat also. It was bird-like in structure, with a flexible, elongated neck and stout body. ''Segisaurus'' was three-toed and had powerful legs that were long compared to its body length. Like its legs, ''Segisaurus'' had a long tail and long forearms. Its furcula bone was not unl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately 143.1 Mya. The Jurassic constitutes the second and middle period of the Mesozoic, Mesozoic Era as well as the eighth period of the Phanerozoic, Phanerozoic Eon and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province (CAMP). The beginning of the Toarcian Age started around 183 million years ago and is marked by the Toarcian Oceanic Anoxic Event, a global episode of Anoxic event, oceanic anoxia, ocean acidification, and elevated global temperatures associated with extinctions, likely caused by the eruption of the Kar ...

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] |
Triassic
The Triassic ( ; sometimes symbolized 🝈) is a geologic period and system which spans 50.5 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.4 Mya. The Triassic is the first and shortest period of the Mesozoic Era and the seventh period of the Phanerozoic Eon. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
