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 ...
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.
Palaeobatrachidae is an extinct family of frogs known from the Late Cretaceous to the Pleistocene primarily of Europe. They were highly adapted to aquatic life, like other members of the Pipimorpha. The oldest undoubted records of the family are from the lower Campanian (83.6-77.9 million years ago) of France.
Paleontologists have discovered a previously unknown ancient species: Kermitops — an amphibian that predates the dinosaurs and reveals the complexity of frog evolution. Researchers found a tiny ...
This big cat is found much more rarely than the contemporary Smilodon. Within the species itself, more fossil specimens are thought to represent males. [28] Bobcat [29] [12] Lynx rufus: Bobcats are rare compared to other cats at La Brea. Van Valkenburgh suggests that they may have lived at the fringe of the predator community. Cougar [15] [30 ...
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 ...
Previous fossil amphibians had many more presacral vertebrae than this and T. massinoti provides a missing link between salamanders and frogs. Other characteristics that distinguish it from modern frogs include the possession of a short tail with unfused vertebrae, a separate radius and ulna in the fore limb, and separate tibia and fibula in ...
