During Mesozoic and early Tertiary times the Crocodylomorphs were much more diverse than they are now.
They were originally small, lightly built, active land animals. These were replaced during the early Jurassic by various aquatic and marine forms. The later Jurassic, Cretaceous, and Tertiary saw a wide diversity of terrestrial and semi-aquatic lines.
Modern crocodilians do not appear until the Upper Cretaceous.
