can u give the time when were they alive
Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous.

Jawless fish can also be known as Agnatha which appeared on earth roughly about 530 million years ago.
Dinosaurs appeared on earth around 247 million years ago and gone extinct around 65.5 million years ago
Angiosperms first appeared in the lower cretaceous on earth roughly about 125 million years ago.
