Palaeobatrachus was the first fossil frog to be described, [1] with the first species being P. diluvianus named by Goldfuss in 1831, originally as Rana diluviana from remains found in uppermost Oligocene strata near Bonn in Germany. It was later recognised as distinct and placed in the new separate genus Palaeobatrachus by Tschudi in 1839. [3]
Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends. Another term, "zone fossil", is used when the fossil has all the characters stated above except wide geographical distribution; thus, they correlate the surrounding rock to a biozone rather than a specific time period.
Beelzebufo (/ b iː ˌ ɛ l z ɪ ˈ b juː f oʊ / or / ˌ b iː l z ə ˈ b juː f oʊ /) is an extinct genus of hyloid frog from the Late Cretaceous Berivotra and Maevarano Formations of Madagascar. [1] The type species is B. ampinga, and common names assigned by the popular media to B. ampinga include devil frog, [2] devil toad, [3] and the ...
The large, round head and shortened vertebral column are features Gerobatrachus shares in common with frogs and the early salamander Karaurus. [1] [2] Gerobatrachus also has a large embayment at the back of the skull called an optic notch, which is seen other amphibolids and in frogs and supports the tympanum, an eardrum-like structure used in ...
Temnospondyli (from Greek τέμνειν, temnein 'to cut' and σπόνδυλος, spondylos 'vertebra') or temnospondyls is a diverse ancient order of small to giant tetrapods—often considered primitive amphibians—that flourished worldwide during the Carboniferous, Permian and Triassic periods, with fossils being found on every continent.
There definitely were no muppets during the Permian Period, but there was a Kermit - or at least a forerunner of modern amphibians that has been named after the celebrity frog. Scientists on ...
In 2024, a tadpole specimen of N. degiustoi (MPM-PV 23540) was reported from the La Matilde Formation of Argentina, representing the oldest known tadpole and the first stem-anuran larva in the fossil record. Tadpoles of this species reached lengths of 15.9 centimetres (6.3 in), among the largest recorded in frogs living or extinct.
