Diplocaulus had a stocky, salamander-like body, but was relatively large, reaching up to 1 m (3.3 ft) in length. Although a complete tail is unknown for the genus, a nearly complete articulated skeleton described in 1917 preserved a row of tail vertebrae near the head.
Scientists have revealed fossils of a giant salamanderlike beast with sharp fangs that ruled waters before the first dinosaurs arrived. The predator, which was larger than a person, likely used ...
Further salamander fossils are known from the Middle Jurassic of England, [58] Scotland, [59] China, [60] and Kazakhstan. [61] The oldest known crown-group salamander remains uncertain but recent analyses suggest it is Valdotriton from the Late Jurassic of Spain. [59]
As the fossil record for the Cryptobranchidae shows an Asian origin for the family, how these salamanders made it to the eastern US has been a point of scientific interest. Research has indicated a dispersal via land bridge , with waves of adaptive radiation seeming to have swept the Americas from north to south.
Andrias scheuchzeri is an extinct species of giant salamander belonging to the genus Andrias, which also contains the closely related living Asian giant salamanders.It is known from Oligocene to Pliocene aged deposits primarily from Central Europe, but possibly as far east as Western Siberia and eastern Kazakhstan.
While only the skull - measuring around 1.2 inches (3 cm) long - was discovered, the researchers think Kermitops had a stoutly built salamander-like body roughly 6-7 inches (15-18 cm) long, though ...
The Chinese giant salamander (Andrias davidianus) is one of the largest salamanders and one of the largest amphibians in the world. [4] It is fully aquatic, and is endemic to rocky mountain streams and lakes in the Yangtze river basin of central China.
