Natural History Museum, Berlin
The Natural History Museum () is a natural history museum located in Berlin, Germany. It exhibits a vast range of specimens from various segments of natural history and in such domain it is one of three major museums in Germany alongside Naturmuseum Senckenberg in Frankfurt and Museum Koenig in Bonn. The museum houses more than 30 million zoological, paleontological, and mineralogical specimens, including more than ten thousand type specimens. It is famous for two exhibits: the largest mounted dinosaur in the world (a ''Giraffatitan'' skeleton), and a well-preserved specimen of the earliest known bird, ''Archaeopteryx''. The museum's mineral collections date back to the Prussian Academy of Sciences of 1700. Important historic zoological specimens include those recovered by the German deep-sea Valdiva expedition (1898–99), the German Southpolar Expedition (1901–03), and the German Sunda Expedition (1929–31). Expeditions to fossil beds in Tendaguru in former Deutsch Os ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cymbospondylus Nichollsi
''Cymbospondylus'' (meaning "cupped vertebrae") is an extinct genus of large ichthyosaurs, of which it is among the oldest representatives, that lived from the Lower to Middle Triassic in what are now North America and Europe. The first known fossils of this taxon are a set of more or less complete vertebrae which were discovered in the 19th century in various mountain ranges of Nevada, in the United States, before being named and described by Joseph Leidy in 1868. It is in the beginning of the 20th century that more complete fossils were discovered through several expeditions launched by the University of California, and described in more detail by John Campbell Merriam in 1908, thus visualizing the overall anatomy of the animal. While many species have been assigned to the genus, only five are recognized as valid, the others being considered synonymous, doubtful or belonging to other genera. ''Cymbospondylus'' was formerly classified as a representative of the Shastasauridae, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caviramus Schesaplanensis
''Caviramus'' is a genus of caviramid pterosaur from the Late Triassic (early Rhaetian-age) lower Kössen Formation of the Northern Calcareous Alps of Switzerland. The genus was in 2006 named by Nadia Fröbisch and Jörg Fröbisch. The type species is ''Caviramus schesaplanensis''. The genus name is derived from Latin ''cavus'', "hollow" and ''ramus'', "branch". The specific name refers to Mount Schesaplana. Description The genus is based on holotype PIMUZ A/III 1225, three non-contiguous fragments of a ramus (lower jaw) of the mandible with multicuspate teeth. Two teeth are preserved, one with three cusps, and one with four; despite this difference the authors consider them as essentially isodont. The number of teeth is estimated at a minimum of twelve and a maximum of seventeen. A row of large oval foramina runs parallel to the tooth row; foramina in the form of small holes in the anterior part of the lower jaw suggest some sort of soft-tissue structure, or a keratin cove ...

Pasawioops
''Pasawioops'' is an extinct genus of early Permian dissorophoid temnospondyl within the clade Amphibamiformes. History of study ''Pasawioops'' was first described from the early Permian fissure fills near Richards Spur in Comanche County, Oklahoma. It is known from three skulls from this locality. The holotype is a complete skull (reposited at the Sam Noble Oklahoma Museum of Natural History The Sam Noble Oklahoma Museum of Natural History is the officially designated natural history museum for the State of Oklahoma, located on the campus of the University of Oklahoma. The museum was founded in 1899 by an act of the Oklahoma Terri ... MNH, while the referred specimens are larger but more incomplete partial skulls (one at the OMNH and the other at the Field Museum). The taxon is also known from one specimen from the early Permian of Texas (reposited at the Museum of Comparative Zoology), being previously misidentified as a specimen of ''Tersomius texensis''.

Gerobatrachus Hottoni
''Gerobatrachus'' is an extinct genus of amphibamid temnospondyl (represented by the type species ''Gerobatrachus hottoni'') that lived in the Early Permian, approximately 290 million years ago (Ma), in the area that is now Baylor County, Texas. When it was first described in 2008, ''Gerobatrachus'' was announced to be the closest relative of Batrachia, the group that includes modern frogs and salamanders. It possesses a mixture of characteristics from both groups, including a large frog-like head and a salamander-like tail. These features have led to it being dubbed a frogamander by the press. Some more recent studies place ''Gerobatrachus'' as the closest relative of Lissamphibia, the group that contains all modern amphibians including frogs, salamanders, and caecilians, or place modern amphibians far from ''Gerobatrachus'' within a group called Lepospondyli. Description The only known specimen of ''Gerobatrachus'' is a nearly complete skeleton (USNM 489135) about long, tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cacops Woehri
''Cacops'' ("ugly look" for its strange appearance), is a genus of dissorophid temnospondyls from the Kungurian stage of the early Permian of the United States. ''Cacops'' is one of the few olsoniforms (dissorophids and the larger trematopids) whose ontogeny is known. ''Cacops'' fossils were almost exclusively known from the Cacops Bone Bed of the Lower Permian Arroyo Formation of Texas for much of the 20th century. New material collected from the Dolese Brothers Quarry, near Richards Spur, Oklahoma in the past few decades has been recovered, painting a clearer picture of what the animal looked and acted like. History of discovery ''Cacops aspidephorus'' is the most famous dissorophid, in part due to a majority of its skeleton having been known for over a century. Over 50 specimens have been found in the ''Cacops'' Bone Bed in Baylor County, Texas, which is now flooded by the dammed Lake Kemp. However, many of the specimens are covered in calcite, which penetrates the bone ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thalattoarchon Saurophagis
''Thalattoarchon'' is a genus of large, Middle Triassic Predation, predatory ichthyosaur from North America, containing the single species ''T. saurophagis''. The taxon was described in 2013 from a single specimen discovered in the Favret Formation in Nevada. The Binomial nomenclature, generic name, meaning "ruler of the seas", refers to its status as an apex predator, while the Specific name (zoology), specific epithet, meaning "lizard eater", alludes to its Carnivore, carnivorous diet. The Phylogenetic nomenclature, classification of this genus within the ichthyosaurs is much debated, being either classified within the clade Merriamosauria or in the more Basal (phylogenetics), basal family Cymbospondylidae. As an ichthyosaur, ''Thalattoarchon'' had Flipper (anatomy), flippers for Limb (anatomy), limbs and a caudal fin, fin on the tail. The size of this large ichthyosaur is estimated around long, although the authors are uncertain about the exact measurements. The animal has a ...

Reiszerpeton Renascentis
''Reiszerpeton'' is an extinct genus of dissorophid temnospondyl known from the Early Permian Archer City Formation of Texas. It is known solely from the holotype, MCZ 1911, a complete skull. This specimen was originally referred to the amphibamiform '' Tersomius texensis''. A reappraisal of the holotype of ''T. texensis'' and a number of other referred specimens by Maddin et al. (2013) noted a number of differences from both ''T. texensis'' and amphibamiforms more broadly that suggested affinities with the Dissorophidae. This was confirmed by a phylogenetic analysis, which placed it as the sister taxon to the Eucacopinae (''Cacops'' + '' Zygosaurus'' + ''Kamacops''). ''Reiszerpeton'' is known only from the type species, ''R. renascentis'', which was named for Canadian paleontologist Robert Reisz Robert Rafael Reisz is a Canadian paleontologist and specialist in the study of early amniote and tetrapod evolution.
