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 have ever been considered to be amphibians, excluding purely vernacular terms. 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. If two or more genera are formally designated and the type specimens are later assigned to the same genus, the first to be published (in chronological order) is the senior sy ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clea ...

Amphibamus
''Amphibamus'' is a genus of amphibamid temnospondyl amphibians from the Carboniferous (middle Pennsylvanian) of North America North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and th ....

Altanulia
''Altanulia'' is an extinct genus of prehistoric amphibian. Description The holotype of ''Altanulia'' - PIN 553/300 -, consisting of an isolated 20 mm long maxilla bearing 45-47 teeth, was found by the Soviet-Mongolian Paleontological Expedition in the southern Gobi Desert, Nemegt Formation, and dates from the Upper Cretaceous (Upper Campanian-Lower Maastrichtian). ''Altanulia'' was diagnosed on the basis in the "Posterior part of maxilla deep, with longitudinal wedge-shaped labial depression; pterygoid tubercle of maxilla well expressed; frontal process in anterior part of bone." Classification ''Altanulia'' belongs to the Discoglossidae, due to the shape and structure of the lingual surface of its maxilla.

Almasaurus
''Almasaurus'' is an extinct genus of trematosaurian temnospondyl within the family Latiscopidae. It is known from several skulls and some postcranial material found from the Argana Formation in Morocco, which dates back to the Late Triassic. When it was first named in 1972, ''Almasaurus'' was placed within its own superfamily, the Almasauroidea. Although the related latiscopid '' Latiscopus disjunctus'' possesses exoccipitals that are underplated (a feature that suggests that it is a member of the family Trematosauridae) ''Almasaurus'' is not considered to be a trematosaurid because it lacks such underplating. ''Almasaurus'' was considered to be a capitosaurian by Warren & Black (1985) because it shared several characters with the group, including a deeply notched squamosal and a lacrimal flexure, while supposedly exhibiting none of the characters associated with trematosaurians. However, more recent studies have concluded that ''Almasaurus'' is either a temnospondyl more ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Albionbatrachus
''Albionbatrachus'' is an extinct genus of prehistoric frogs from England and Romania. Two species are recognized: While previously synonymised with ''Palaeobatrachus'', it is now considered a distinct palaeobatrachid genus based on characters of the frontoparietals. *''Albionbatrachus oligocenicus'' *''Albionbatrachus wightensis''C.

Albanerpeton
''Albanerpeton'' is an extinct genus of salamander-like lissamphibian found in North America and Europe, first appearing in Cretaceous-aged strata. There are eight described members of the genus, and one undiagnosed species from the Paskapoo Formation, with the most recent, ''A. ektopistikon'' being described by Carrano ''et al.''in 2022. Members of the genus had a robust head and neck which likely allowed them to actively burrow, characteristic of fossorial species, and they lived in a wide range of environments. This genus of amphibian was the last of its order, surviving until the late Pliocene in southern Europe, and into the Early Pleistocene (Gelasian) of northern Italy. It likely became extinct when the region developed its present Mediterranean-type climate, having preferred one that was cold and humid. The monophyly of ''Albanerpeton'' has recently been questioned History and Discovery Albanerpeton was first described by Estes and Hoffstetter in 1976. However, the genus ...

Adamanterpeton
''Adamanterpeton'' is a genus of edopoid temnospondyl within the family Cochleosauridae. Two specimens were discovered in the fossil-rich Allegheny Formation of Linton, Ohio. The type species ''A. ohioensis'' was named in 1998. ''Adamanterpeton'' is rare in the Linton vertebrate assemblage, with other amphibians like '' Sauropleura'', ''Ophiderpeton'', and ''Colosteus ''Colosteus'' is an extinct genus of colosteid tetrapod from the Late Carboniferous (late Westphalian stage) of Ohio.

Actiobates
''Actiobates'' is an extinct genus of trematopid temnospondyl that lived during the Late Carboniferous. It is known from the Garnett Quarry in Kansas. History of study ''Actiobates peabodyi'' was named in 1973 by Theodore Eaton. The genus name derives from the Greek words ' ("shore") and ' ("walker"), referring to the estuarine nature of the Garnett Quarry deposits, and the specific name is for the American paleontologist Frank Peabody. The taxon is based on a single specimen represented by a partial skull and associated postcranial skeleton that is currently deposited at the University of Kansas Natural History Museum. Anatomy The holotype of ''A. peabodyi'' is dorsoventrally compressed, obscuring many details of the anatomy. Schoch & Milner (2014) listed only one diagnostic feature for the taxon, a quadratojugal excluded from the smooth ventral border of the otic notch. Relationships Eaton (1973) originally classified ''Actiobates'' as a dissorophid but only because he cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
