Natural History Museum, Berlin
The Natural History Museum (german: Museum für Naturkunde) 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).

Cymbospondylus Nichollsi
''Cymbospondylus'' (a Greek word meaning "boat vertebrae") was a basal early ichthyosaur that lived between the early and middle Triassic period (249-237 million years ago). Previously, the genus was classified as a shastasaurid, but more recent work finds it to be more basal.Motani, R. 1999: Phylogeny of the Ichthyopterygia. Journal of Vertebrate Paleontology. 19 (3): 473 – 496 ''Cymbospondylus'' was a cosmopolitan genus found in Nevada, Europe (Switzerland, Germanic Basin) and Spitsbergen. History ''Cymbospondylus'' was described from Nevada by Joseph Leidy in 1868 on the basis of several fragmentary vertebrae which he assigned to two different species: ''C. piscosus'' (the type species) and ''C. petrinus''. The University of California, under the direction of John Campbell Merriam and funded by Annie Alexander, conducted extensive fieldwork in the region in the late nineteenth and early twentieth century, following the description of ''Cymbospondylus'', recoverin ...

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 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''. Anatomy ''Pasawioops'' has a relatively long and slender skull for an amphibamiform, with the posterior skull table not abbreviated as in more derived taxa. A tooth-bearing crest is found along the cultriform process, and the pterygoid bears two ridges of teeth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, that i ... [...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 tis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thalattoarchon Saurophagis
''Thalattoarchon'' is an extinct genus of ichthyosaur from the Middle Triassic of the western United States. The type species ''Thalattoarchon saurophagis'' (meaning "lizard-eating sovereign of the sea" in Greek language, Greek) was discovered in Nevada, USA, in 2010 and formally described in 2013. It is known from a single skeleton, holotype FMNH PR 3032, consisting of a partial skull, vertebral column, hip bones, and parts of the hind fins. The total length of ''Thalattoarchon'' is estimated to have been at least . ''Thalattoarchon'' is thought to have been one of the first marine macropredators capable of eating prey that was similar in size to itself, an ecological role that can be compared to that of modern orcas. ''Thalattoarchon'' lived four million years after the first appearance of ichthyosaurs in the Early Triassic and is therefore the oldest known marine reptile to have been an apex predator. It lived eight million years after the Permian-Triassic extinction event, indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Research career Reisz received his B.Sc. (1969), M.Sc. (1971) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biological Reviews
The Cambridge Philosophical Society (CPS) is a scientific society at the University of Cambridge. It was founded in 1819. The name derives from the medieval use of the word philosophy to denote any research undertaken outside the fields of law, theology and medicine. The society was granted a royal charter by King William IV in 1832. The society is governed by an elected council of senior academics, which is chaired by the Society's President, according to a set of statutes. The society has published several scientific journals, including ''Biological Reviews'' (established 1926) and ''Mathematical Proceedings of the Cambridge Philosophical Society'' (formerly entitled ''Proceedings of the Cambridge Philosophical Society'', published since 1843). ''Transactions of the Cambridge Philosophical Society'' was published between 1821–1928, but was then discontinued.
