Fur to Frogs

©Nobu Tamura; released as Palaeobatrachus gigas
Palaeobatrachus is a genus consisting of at least two named species, P. occidentalis and P. robustus (with others being mentioned that we will explore later), of amphibian that appears in the fossil record from approximately 130 MA to 11.6 MA; Fossilworks reports a range of 70 MA to 9.7 MA and these disparate ranges will be figured out later this week. An early frog, Palaeobatrachus is known from central Europe. Specifically, Palaeobatrachus is very common in the freshwater fossils of Germany. Early frogs, Palaeobatrachus, was extremely amphibious and spent very little time out of water. A lot is know about the entire life cycle of Palaeobatrachus with all stages of life, egg, tadpole, and adult, having been recovered from Bohemian rocks. Changing temperatures and changes in available suitable water sources caused Palaeobatrachus to suffer a reduced range of habitat. This, in the end, forced the frogs into extinction as continual climate change and shrinking suitable habitat forced the frog into what would be a losing battle with other taxa and the environment.
