pleurodiran
Pleurodirans are a group of extinct reptiles that lived during the Triassic and Jurassic periods, approximately 250 to 175 million years ago. They are characterized by their unique body structure, which includes a long, flat body and a large, flat head. Pleurodirans are believed to have been semi-aquatic, with their flat bodies and webbed limbs adapted for swimming. They are also known for their distinctive teeth, which were adapted for crushing and grinding food.
Pleurodirans are divided into two main groups: the Erythrosuchidae and the Proterosuchidae. The Erythrosuchidae were small
Pleurodirans are believed to have been active predators, feeding on a variety of small animals and plants.
Pleurodirans went extinct at the end of the Jurassic period, along with many other groups of reptiles.
