Proterogyrinus was an anthracosaur, a large group of reptilian reptiliomorphs. It is likely that the first reptiles, such as Petrolacosaurus, evolved from reptilomorphs. Like other reptiliomorphs, such as Seymouria, Proterogyrinus could venture further away from water than most amphibians.

Species[]

There are two known species in the genus Proterogyrinus;

  • Proterogyrinus pancheni
  • Proterogyrinus scheelei

Information[]

During the Late Carboniferous period (326 - 318 million years ago), the amphibians were an exciting and diverse group of animals that had come to dominate the waterlogged forest world. They also were evolving into reptiles, which produced the unique and interesting reptiliomorphs.

Proterogyrinus was one of the largest of its region, and was perfectly adapted for life in the swamps. It was a top predator that hunted both on land and in the water. Its powerful jaws had sharp teeth that could handle animals that were quite large, such as fish, large arthropods and other reptiles and amphibians.

Proterogyrinus was similar in shape to other prehistoric amphibians and reptiliomorphs, such as Crassigyrinus and Eryops. It was about seven to eight feet long, similar in size to the biggest modern lizards.

Most Carboniferous amphibians were good swimmers and could move fast through the rivers, lakes and bogs surrounding the lowland forests, but also could walk on land like some amphibians today. Many species either stayed in the water at all times or could only wriggle through the mud on the banks; reptiliomorphs ventured further into the forest. Being able to hunt away from the waters edge meant that Proterogyrinus could catch food in places where its rivals could not go. It also meant that it could escape water-borne enemies, such as predatory fish, by clambering on shore, or over the logs and other obstacles that frequently choked on the swamps' river channels.

Fossils have been found in Scotland and West Virginia.
