When did the dinosaur live?

Answer 1

Dinosaurs lived throughout the Mesozoic Era, which began 245 million years ago and lasted for 180 million years. It is sometimes called the Age of the Reptiles. The era is divided into three periods: Triassic, Jurassic, and Cretaceous.

Answer 2

Dinosaurs first appeared in the Triassic period about 230 million years ago. Non-avian dinosaurs roamed the earth until about 65 million years ago and then were wiped out, most like by the impact of an asteroid or comet. Birds, which are now classified with the dinosaurs, continue to live to this day.
Dinosaurs lived on earth for over 160 million years. They were the dominant terrestrial vertebrates from the late Triassic period (around 230 million years ago) to the end of the Cretaceous period (around 65 million years ago). After the Cretaceous-Tertiary extinction event all but a few species of birds became extinct.
during the Triassic-Jurassic-Cretaceous.about 245 million years ago to 75 million years ago.
the first dinosaurs appeared 225,000,000 years ago, and the last dinosaurs died out 65,000,000 years ago
