Yes. Non-avian dinosaurs first appeared in the Triassic period and were around until the end of the Cretaceous period. Birds, which are now classified as dinosaurs, appeared in the late Jurassic and live through the Cretaceous period as well.
Dimetrodon live in the Permian period, which was before the dinosaurs.
Platyhystrix was not a dinosaur. It was an amphibian. Dinosaurs did not evolve until after the permian. But, yes, it was a predator
No, as there was no Cretaceous-Permian extinction. There was the Permian-Triassic extinction, which ocurred before the dinosaurs appeared. Non-avian dinosaurs were wiped out in the Cretaceous-Paleogene extinction.
The Triassic Period is a geological time period that occurred from about 251 to 201 million years ago. It followed the Permian Period and preceded the Jurassic Period in the Mesozoic Era. The Triassic Period saw the diversification of early reptiles and the rise of dinosaurs.
Permian Period.
correct answer isA. Natural History and Permian Period
The Permian Period was ended by the Permian/Triassic Extinction Event, which wiped out 90% of the species on Earth at that time.
Ther Permian was the last period of the Paleozoic era.
(Assuming you mean the Permian Period) Probably the Permian Disaster, in which the Earth was almost sterilized by a runaway greenhouse effect. 90-95% of all life perished, a far greater catasrophe than the one that killed off the dinosaurs, sea serpents, flying reptiles and ammonites.
The trilobites went extinct during the mass extinction at the end of the Permian period.
most dinosaurs died of the meteor but a couple of periods before the cretacious period there was the permian period in which 95% of all life died as all the volcanoes erupted and shot up gas (methane) and killed them. a crocodile/ aligator is a dinosaur, 1 of the remaining dinosaurs alive as all did not die.
The permian period was the end of the paleozoic era.
