Prehistory takes place from the apparition of the first beeing that could be considered human (Australopithecus - 3,2 milions years ago) and to the first writting system (some Balaknian tablets date up to 5300 BC, but ussually the writing in Sumer - 3200 BC is considered the end of Prehistory)

So no dinosaurs in Prehistory, but lotta prehistoric mammals (including Titan Bird!) and of course all kind of human species.
