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]
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 youngest fossils of Palaeobatrachus date to around 500,000 years ago, during the Middle Pleistocene after which they likely became extinct due to increasing aridity and freezing temperatures during the ice ages. [1] Fossils of indeterminate palaeobatrachids are also known from the Pliocene and Early Pleistocene of Western Siberia. [3]
Triadobatrachus is an extinct genus of salientian frog-like amphibians, including only one known species, Triadobatrachus massinoti. It is the oldest member of the frog lineage known, and an excellent example of a transitional fossil. It lived during the Early Triassic about 250 million years ago, in what is now Madagascar.
The fossil was first uncovered in 1984 by the late Nicholas Hotton III, a museum paleontologist who had excavated fossils from the Red Beds in Texas, an area known to be rich in Permian-age remains.
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.
Older fossils lay even deeper beneath the bone bed. These 8.9-million-year-old rocks included fossilized bones of fish and marine mammals. Experts also found teeth from juvenile megalodons and ...
Tailed frog size compared to a dime. The existence of the visible "tail" appendage makes this frog family distinct from all other frogs. It is usually classified in the ancient frog suborder Archaeobatrachia and further organized into a basal clade with Leiopelma that is considered a sister taxon to all other frogs. [7]
