permian period
The Triassic Period occurred before the Jurassic Period. The Triassic Period lasted from about 251 million to 201 million years ago, while the Jurassic Period followed, lasting from about 201 million to 145 million years ago.
The Triassic period came before the Jurassic period in geologic time. The Triassic period lasted from around 251 million to 201 million years ago, followed by the Jurassic period, which lasted from around 201 million to 145 million years ago.
Carboniferous Silurian Ordovician Devonian Cambrian Pre Cambrian
Triassic came before
Yes. all the PROSAUROPODS lived in the triassic period. PRO means before, SAUROPOD means long necked dinosaurs that lived in the JURASSIC and CRETACEOUS. PROSAUROPODS, on the other hand, lived in the TRIASSIC.
yes the first dinos appeared 230mya during the late triassic period
That is easy, the first is precambrian time, next you get the paleozoic era, which has Cambrian, ordovician, silurian, denovonian, carbonferious periods, Next you get the mesozoic era which contains the next three, which are triassic, jurrasic, and cretacous periods. Lasty you get the Cenozoic era which contains the last two which are the tertiary, and the quaternary!
the first dinos appeared 230mya during the late triassic period so it was well before the dinos time : )
The first mammals appeared in the Triassic Period of the Mesozoic Era, when dinosaurs had already been present for at least 9 million years.
Mammals came before birds. The first mammals lived in the Triassic and the first birds lived in the Jurassic.
