Batrachosauroididae
Batrachosauroididae is an extinct family of prehistoric salamanders with holarctic distribution. They were paedomorphic and presumably aquatic. They are possibly the sister taxon of Proteidae, an extant family of aquatic salamanders. They are definitively known from the Late Cretaceous to Miocene of North America and Europe. Remains from the earliest Cretaceous (Berriasian) Lulworth Formation of England have tenatively been attributed to this family. The following genera are included: *'' Batrachosauroides'' United States, Eocene-Miocene *''Opisthotriton'' North America, Late Cretaceous-Paleocene *'' Palaeoproteus'' Europe Paleocene-Miocene *'' Parrisia'' United States, Late Cretaceous *'' Peratosauroides'' United States, Miocene *'' Prodesmodon'' North America Late Cretaceous-Paleocene See also * Prehistoric amphibian * List of prehistoric amphibians This list of prehistoric amphibians is an attempt to create a comprehensive listing of all genera from the fossil record that ha ...

Lulworth Formation
The Lulworth Formation is a Formation (geology), geologic formation in England. It dates from the late Tithonian to the mid Berriasian. It is a subunit of the Purbeck Group. In Dorset, it consists of three members, which are in ascending order, the Mupe Member, the Ridgway Member, and the Warbarrow Tout Member. The Mupe Member is typically 11 to 16 m thick and largely consists of marls and micrites with interbeds of calcareous mudstone. The Ridgeway Member is about 3 to 7 m thick and consists of in its western portion carbonaceous muds, marls and micrites, in the east the muds are replaced by micritic limestone. The Warbarrow Tout Member is 17 to 39 m thick and consists of limestone at the base and micrite and mudstone for the rest of the sequence, this member is the primary source of the vertebrate fossils within the formation. Elsewhere the unit is undifferentiated. Vertebrate paleobiota Amphibians Turtles Lepidosaurs Crocodyliformes Dinosaurs Mammals ...

Batrachosauroides
''Batrachosauroides'' is an extinct genus of prehistoric salamander known from several sites across the United States. The two identified species are ''Batrachosauroides dissimulans'' (Taylor and Hesse, 1945) and ''Batrachosauroides gotoi'' (Estes, 1969). A proposed, unidentified third species has been proposed by paleontologist James Gardner based on the discovery of a dental fossil in the Bushy Tailed Blowout area of the Lance Formation fossil grounds, but has not been definitively identified as a new species or as part of either of the two identified species.

Cretaceous First Appearances
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth by the ...

The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ('' nomina dubia''), or were not formally published (''nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered amphibians. Modern forms are excluded from this list. The list currently includes 454 names. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously published name.

Walter Auffenberg
Walter Auffenberg ( – ) was an American biologist who spent almost 40 years in field research, studying reptile and amphibian paleontology and the systematics and biology of numerous reptile species, including alligators and Komodo dragons. Early life Auffenberg was born in Detroit, Michigan in 1928. After graduating high school, he relocated to DeLand, Florida to work on two small citrus groves owned by his parents. Shortly after, he enlisted in the US Navy and trained as a Hospital Corpsman in Corpus Christi, Texas. Upon his discharge he returned to Florida and attended Stetson University in DeLand, receiving his Bachelor of Science in Zoology in 1951. He moved to Gainesville, Florida to obtain his advanced degrees at the University of Florida. Academic life Auffenberg received his M.Sc. from the University of Florida in 1953 with his thesis A Study of Geographic Morphological Variation in the Blacksnake. He held a temporary position as Curator of Vertebrate Paleontology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
