Batrachosuchus browni Broom 1903 The type locality of Batrachosuchus browni is in the Burgersdorp Formation at Aliwal North Area in South Africa. The strata in which the remains were found is dated to a span of 249.7 – 237 million years ago (Olenekian-Anisian).
The length of Batrachosuchus browni was about 50 cm. (1.6 ft.).
The different species are distinguished mainly by details of skull shape.

The world’s oldest fossil of a salamander has been discovered. Six fossils of 157 million year old salamanders were found embedded in volcanic ash in an ancient lake bed in western Liaoning Province, China. The ash helped keep the fossil remarkably well preserved. The Jurassic salamander has been given the name, Beiyanerpeton jianpingensis. These fossils take salamanders back another 40 million years into the Oxfordian stage of the Late Jurassic. The previous oldest salamander fossil was a 114 million year old fossil found in Spain.
The ancient 4-inch long Jurassic salamanders resembled modern salamanders. The researchers say differences between the fossil and modern salamndroids include “a discrete and tooth-bearing palatine, and unequivocally nonpedicellate and monocuspid marginal teeth in large and presumably mature individuals.”
The research is published here in the Proceedings of the National Academy of Sciences(PNAS).
This is a fine exemple of a Branchiosaurus sp. from the Lower Permian of Germany. Approximately 260,000,000 years old.
three adults and one larval Branchiosaurs. These salamander-like amphibians once inhabited swamps in what is now Southwest Germany. This fossil plate comes from a quarry near Pfalz, Germany
Although Branchiosaurs look like modern day salamanders they are not related and are classified in a separate order and family of amphibians. The name branchiosaur means “gill lizard”. As adults Branchiosaurs retained their external gills similar to a modern day amphibians like the mudpuppy (Necturus). Google fossilream to see more of our incredible fossils.
