A Brazilian scientist has identified fossils of a small crocodile-like reptile that lived during the Triassic Period several million years before the first dinosaurs. The fossils of the predator ...
Protosuchus (from Greek: protos, "first" and Greek: souchos, "crocodile") [1] is an extinct genus of carnivorous crocodyliform from the Early Jurassic.
