Werner Janensch
Werner Ernst Martin Janensch (11 November 1878 – 20 October 1969) was a German paleontologist and geologist. Biography Janensch was born at Herzberg (Elster). In addition to Friedrich von Huene, Janensch was probably Germany's most important dinosaur specialist from the early and middle twentieth century. His most famous and significant contributions stemmed from the expedition undertaken to the Tendaguru Beds in what is now Tanzania. As leader of an expedition (together with Edwin Hennig) set up by the Museum für Naturkunde in Berlin, where he worked as a curator, Janensch helped uncover an enormous quantity of fossils of late Jurassic period dinosaurs, including several complete ''Brachiosaurus'' skeletons, then the largest animal ever known. During his long subsequent career (he worked in Berlin from 1914 to 1961), Janensch named several new dinosaur taxa including ''Dicraeosaurus'' (1914) and ''Elaphrosaurus'' (1920). Janensch's ''Brachiosaurus'' were later determ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protacmon
''Diademodon'' is an extinct genus of cynodonts. It was about long. Discovery Harry Seeley had found his fossil in the Burgersdorp Formation of the Beaufort Group in the Karoo Basin of South Africa. As late as 1988, ''Diademodon'' had been considered a Gophodont due to its transversely expanded cheek teeth, however, it has since been placed in the Cynodont order due to significant differences in skull morphology. Additional species were named by paleontologist A. S. Brink in 1979, although they are now considered synonyms of the type species ''Diademodon tetragonus''. Fossils of the ''Diademodon tetragonus'' have more recently been found in the Omingonde Formation of Namibia, the Fremouw Formation of Antarctica, the Ntawere Formation of Zambia and the Río Seco de la Quebrada Formation in Mendoza Province, Argentina. Although ''Diademodon'' is the most well accepted name for the genera to date, it was originally named ''Cynochampsa laniarius'' by Owen in 1860. Th ...

Moschorhinus DB
''Moschorhinus'' is an extinct genus of therocephalian in the family Akidnognathidae with only one species: ''M. kitchingi''. It was a carnivorous synapsid which has been found in the Late Permian to Early Triassic of the South African Karoo Supergroup. It was a large carnivore, reaching in total body length with the largest skull comparable to that of a lion in size. It had a broad, blunt snout which bore long, straight canines. It appears to have replaced the gorgonopsids ecologically, and hunted much like a big cat. While most abundant in the Late Permian, it survived a little after the Permian Extinction, though these Triassic individuals had stunted growth. Taxonomy The genus name ''Moschorhinus'' is derived from the Ancient Greek words μόσχος (mos'-khos) ''moschos'' for calf or young animal, and ''rhin/rhino-'' for nose or snout, in reference to its short, broad snout. The species name, ''kitchingi'', refers to Mr. James Kitching, who originally found (but di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Broomisaurus
''Broomisaurus'' is an extinct genus of Gorgonopsia. It was first named by Joleaud in 1920, and contains the single species ''B. planiceps''. Gebauer (2007) considered ''Broomisaurus'' to be a ''nomen dubium'', indistinguishable as a separate taxon of gorgonopsian because it is based on only a fragmentary remains. A 2015 paper on ''Eriphostoma ''Eriphostoma'' is an extinct genus of gorgonopsian therapsids known from the Middle Permian (middle Capitanian stage) of ''Tapinocephalus'' Assemblage Zone, South Africa.

Abydosaurus
''Abydosaurus'' (meaning " Abydos lizard") is a genus of brachiosaurid sauropod dinosaur known from skull and postcranial material found in upper Lower Cretaceous rocks of northeastern Utah, United States. Discovery ''Abydosaurus'' is one of the few sauropods known from skull material, with the first described complete skull for a Cretaceous sauropod from the Americas. It is also notable for its narrow teeth, as earlier brachiosaurids had broader teeth. ''Abydosaurus'' is based on the holotype DINO 16488, a nearly complete skull and lower jaws with the first four neck vertebrae. Abundant skull and postcranial bones were found at the same site, including partial skulls from three additional individuals, a partial hip and associated tail vertebrae, a shoulder blade, an upper arm bone, and hand bones. These fossils were found in a sandstone bed at the base of the Mussentuchit Member of the Cedar Mountain Formation, near the old visitor center of Dinosaur National Monument. ...

Alopecopsis
''Theriognathus'' (from Greek therion: beast, mammal, Greek, gnathos, “jaw,” +us, pronounced THEH-ree-OG-nah-thuss) is an extinct genus of therocephalian therapsid belonging to the family Whaitsiidae, known from fossils from South Africa, Zambia, and Tanzania. ''Theriognathus'' has been dated as existing during the Late Permian. Although ''Theriognathus'' means mammal jaw, the lower jaw is actually made up of several bones as seen in modern reptiles, in contrast to mammals. ''Theriognathus'' displayed many different reptilian and mammalian characteristics. For example, ''Theriognathus'' had canine teeth like mammals, and a secondary palate, multiple bones in the mandible, and a typical reptilian jaw joint, all characteristics of reptiles. It is speculated that ''Theriognathus'' was either carnivorous or omnivorous based on its teeth, and was suited to hunting small prey in undergrowth. This synapsid adopted a sleek profile of a mammalian predator, with a narrow snout and aroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambeosaurus
''Lambeosaurus'' ( , meaning " Lambe's lizard") is a genus of hadrosaurid dinosaur that lived about 75 million years ago, in the Late Cretaceous period (Campanian stage) of North America. This bipedal/quadrupedal, herbivorous dinosaur is known for its distinctive hollow cranial crest, which in the best-known species resembled a mitten. Several possible species have been named, from Canada, the United States, and Mexico, but only the two Canadian species are currently recognized as valid. Material relevant to the genus was first named by Lawrence Lambe in 1902. Over twenty years later, the modern name was coined in 1923 by William Parks, in honour of Lambe, based on better preserved specimens. The genus has a complicated taxonomic history, in part because small-bodied crested hadrosaurids now recognized as juveniles were once thought to belong to their own genera and species. Currently, the various skulls assigned to the type species ''L. lambei'' are interpreted as showi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eucnemesaurus
''Eucnemesaurus'' (; meaning "good tibia lizard", for its robust tibiae) is a basal sauropodomorph dinosaur genus usually considered to be a synonym of ''Euskelosaurus''. Recent study by Yates (2006), however, indicates that it is valid and the same animal as putative "giant herrerasaurid" ''Aliwalia''. ''Eucnemesaurus'' was named in 1920 by Egbert Cornelis Nicolaas van Hoepen. The type species is ''Eucnemesaurus fortis''. The specific name means "strong" in Latin. It is based on holotype TrM 119, a partial skeleton including vertebrae, part of a pubis, a femur, and two tibiae. The remains were found by Van Hoepen in the late Carnian- early Norian-age Upper Triassic Lower Elliot Formation of the Slabberts district, Orange Free State, South Africa. Yates assigned the genus to the new family Riojasauridae, with '' Riojasaurus'', usually regarded as a melanorosaurid. ''Aliwalia'' Fossil material now assigned to ''Eucnemesaurus'' was once placed in a separate genus and speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
