The dawn of the Permian period brought the Age of Reptiles, but despite the changing landscape, the amphibians continue to be important. The Permian was largely a time of deserts and dry climates, but the desert streams and the ponds of the oases were full of water-dwellitig animal, and here the amphibians were top of the food pyramid.(dinosaur costume for sale)
Features :The obvious feature of this amphibian is the boomerang-shaped head that seems out of proportion to the rest of the body. Apart from that the body is like that of any other aquatic amphibian – broad and flat, long-tailed, with four toes on the front feet and five on the back. We know the whole growth sequence of Diplocaulus, showing that the head grew from a normal salamander-like shape in the young form to the full boomerang shape in the adult.
I he microsaurs were a group of about 30 tiny amphibians, with small legs and short tails, that were thought to have been restricted to the late Carboniferous and Permian beds. However, the discovery of early-late Carboniferous microsaur Utah aerpcton in 1991 and an unnamed early Carboniferous form in 1995 pushed hack their history considerably. Microbrachis was a typical member of the group.(animatronic dinosaur factory)
Features:The teeth of thiscreature are typical of microsaurs in being flattened from side to side. The small-scale structure of the front teeth suggests that the group may be ancestral to modern amphibians. It has the long body of an aquatic animal, with a flexible backbone of many vertebrae and tiny legs. The presence of external gills throughout life, like the modern axolotl (aquatic salamander), is a phenomenon known as “paedomorphosis” – the retention of juvenile features in an adult stage.
