In the early pre historic period it was only water the whole earth was water it was only very tiny fish. Suddenly small land formed then crocodiles were born it was many years ago till the time of the dinosaurs erupted. The first dinosaurs were in the early Triassic period dinosaurs like dipulodocus. Till then mid Triassic appeared those dinosaurs were still first in timeline but 2nd in timeline early to late. then the late Triassic came round with less sand and some more GIANTS type after the sandy Triassic there came the jurassic were came more Giants and dinosaurs.
