Fossil Reptiles of Great Britain

The amniotes split into three main lineages, the synapsids (mammal-like reptiles and ultimately, the mammals), the diapsids (early forms, dinosaurs, extinct marine reptiles, lizards, snakes, crocodilians and ultimately birds), and the anapsids (primitive groups and turtles).
