  Batrachosuchus browni was a temnospondyl amphibian of the Triassic.
The  systematic paleontology of Batrachosuchus is:Amphibia Linnaeus 1758

Brachyopoidea Lydekker 1885
Brachyopidae Lydekker 1885
Batrachosuchus Broom 1903
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.).
batrachosuchus skull
This excerpt from Palaeos Vertebrates tells about physical characteristics of the family Brachyopidae:The Brachyopids were a group of medium-sized tetrapods characterized by short,broad flat skulls with large eyes situated far forward.
The legs are relativelysmall; the creature would have spent most of its life in streams and lakes,although it may have been quite capable of moving about on land.
The uppermargin of the mouth was armed with large fangs, indicating fish-eating habits.
The different species are distinguished mainly by details of skull shape.

Zo zal het hele skelet van Beelzebufo ampinga eruit hebben gezien. Alleen de witte delen zijn daadwerkelijk gevonden. Het streepje rechts stelt vijf centimeter voor. (PNAS) Evans en haar collega’s bestudeerden de meer dan 60 fossiele fragmenten die in het Bassin Mahajanga ( Madagascar) werden verzameld. Het team kon geen volledig skelet samenvoegen, maar was wel in staat om een bijna volledig beeld van de schedel te reconstrueren ( er waren genoeg schedelbeenderen aanwezig om minstens de linkerhelft te reconstrueren :de andere helft is dan gebaseerd op symetrie ) , die “groot ,dik en uitgerust met een reusachtige mond” bleek te zijn .

Beelzebufo ampigna rana huesos

Beelzebufo was the largest frog that ever lived, weighing about 10 pounds and measuring nearly a foot and a half from head to tail. Judging by its unusually wide mouth, it probably feasted on the occasional baby dinosaur as well as the usual insects.

Beelzebufo was the largest frog that ever lived, weighing about 10 pounds and measuring nearly a foot and a half from head to tail. Unlike contemporary frogs, which are mostly content to snack on insects, Beelzebufo (at least by the evidence of its unusually wide and capacious mouth) must have chowed down on the smaller animals of the late Cretaceous period, perhaps including baby dinosaurs and full-grown “dino-birds” in its diet.
 °
Reprising a common theme, this prehistoric amphibian evolved to its giant size on the relatively isolated Indian Ocean island of Madagascar, where it didn’t have to deal with the large, predatory, theropod dinosaurs that ruled the earth elsewhere.

Beiyanerpeton jianpingensis.

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).

BRANCHIOSAURUS PERMIAN AMPHIBIAN FOSSIL

This is a fine exemple of a Branchiosaurus sp. from the Lower Permian of Germany. Approximately 260,000,000 years old.

Four Rare Fossil Amphibians  - Pfalz, GermanyFour Rare Fossil Amphibians  - Pfalz, GermanyFour Rare Fossil Amphibians  - Pfalz, Germany

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.
