Hyla is a genus of frogs in the tree frog family Hylidae. As traditionally defined, it was a wastebasket genus with more than 300 species found in Europe, Asia, Africa, and across the Americas. After a major revision of the family, most of these have been moved to other genera so that Hyla now only contains 17 extant (living) species from Europe, northern Africa and Asia. The earliest known fossil member of this genus is †Hyla swanstoni from the Eocene of Saskatchewan, Canada, but its designation to Hyla happened before the major revision, meaning that its position needs confirmation.
Eopelobates is an extinct genus of frogs in the family Pelobatidae. Closely related to the living European spadefoot toad, it is known from the Eocene of western North America, and the Eocene–Pliocene of Europe. It is suggested that the distribution over both Europe and North America is due to dispersal during the Paleocene-Eocene Thermal Maximum.
Actiobates is an extinct genus of trematopid temnospondyl that lived during the Late Carboniferous. It is known from the Garnett Quarry in Kansas.
Baurubatrachus is an extinct genus of prehistoric frogs found in the Maastrichtian Marília Formation of Brazil, formerly considered to be related to the extant family Ceratophryidae. However, a detailed assessment of the anatomy and relationships of the single known fossil of Baurubatrachus demonstrated that it is not part of Ceratophryidae and might be part of a much ancient group of Neobatrachia.
Batrachiderpeton is an extinct genus of nectridean lepospondyl within the family Diplocaulidae; it was a basal member of the family. The type species is B. reticulatum and was found in a coal field in Northumberland, England at a locality that also yields the remains of Anthracosaurus russelli. A second species is also known: B. lineatum.
Eoxenopoides is an extinct genus of prehistoric frogs. It is known from Banke, a Maastrichtian/Selandian crater lake mudstone in South Africa.
Eorhinophrynus is an extinct genus of prehistoric frog from Wyoming.
Dolichopareias is an extinct genus of prehistoric amphibian.
Ostodolepis is an extinct genus of microsaur within the family Ostodolepidae. It is known from the Arroyo Formation in Texas.
Mordex is an extinct genus of temnospondyls from Carboniferous of the Czech Republic.
Monsechobatrachus is an extinct genus of prehistoric frogs. It is known from a complete but very poorly preserved skeleton from Monsech in Spain.
Miopelodytes is an extinct genus of prehistoric frog known from Miocene of Nevada.
Miopelobates is an extinct genus of prehistoric frogs in the family Pelobatidae.
Macropelobates is an extinct genus of prehistoric frogs. It was described by Gladwyn Kingsley Noble based on material from Oligocene of Mongolia.
Rewana is an extinct genus of prehistoric temnospondyls. Two species have been described from the Arcadia Formation of Australia.
Vulcanobatrachus is an extinct genus of fossil frog. The genus contains the single species Vulcanobatrachus mandelai found at Marydale, South Africa, described in 2005 and named after Nelson Mandela. The genus owes its name to the fact that fossils were recovered from an extinct volcanic crater lake of Late Cretaceous age. The fossil frogs are assumed to have died following a limnic eruption (a degassing event possibly of CO2) by the volcano.
Wealdenbatrachus is an extinct genus of prehistoric frog known from the Lower Cretaceous of Uña, Spain, which is part of the La Huérguina Formation Its anatomy and relationships have recently been revisited, finding that this frog might be a proficient jumper, and that it was a primitive frog close to the ancestry of all modern frogs.
Theatonius is an extinct genus of Cretaceous amphibians known from North America. Originally described from the Lance Formation, Wyoming, it is now also known from Utah, Montana, and New Jersey.
Llankibatrachus is an extinct genus of prehistoric frogs in the family Pipidae. They are known from the Ypresian (Casamayoran) Huitrera Formation of Argentina.
Schizodus is an extinct genus of shallow marine clams. It lived from the Silurian to Early Jurassic periods.
