What periods did the dinosaurs live in?
Well, their whole period of existence was called the MESOZOIC period. The earliest dinosaurs such as Coelophysis, a predator, appeared in the sub-period called the TRIASSIC, from around 225 million BC to 190 million BC. By the way, Coelophysis was from the late Triassic. Then in the JURASSIC period (210 million BC to 140 million BC as they overlapped slightly), probably the best well known period from the movie ‘Jurassic Park’ (which in fact most of the dinosaurs in it came from the next period), then (again the late Jurassic) sauropods, like Brachiosaurus (you might know it as Brontosaurus, because it was discovered later and named again but the scientific name is Brachiosaurus) were widespread, so the Jurassic is sometimes known as ‘the age of the giants’. Next came the CRETACEOUS period, from 135 million BC until 65 million BC, when all the well known dinosaurs existed, such as T. Rex, Velociraptor, Triceratops, Stegosaurus ETC. Now most of the sauropods had died out, except from th
