Dinosaurs first evolved 231.4 million years ago in Pangaea. This was during the beginning of the Mesozoic era, in the Triassic period.
Dinosaurs evolved first and then some dinosaurs evolved into birds. So all birds are technically dinosaurs.
The first dinosaurs evolved from fishes and were no bigger than these days crocodiles.
No. Dinosaurs evolved from reptiles. Birds evolved from dinosaurs.
Dinosaurs evolved before chickens .
Apparently, according to different sources, fish seem to have been around since the first dinosaurs and before.
Dinosaurs came before birds, because dinosaurs later on evolved into birds, therefore, making birds come along LATER then the dinosaurs. However dinosaurs were far from the first creatures on earth.
They evolved from dinosaurs. So yeah, the egg came first.
Mammals are older. The first mammals evolved around 220 million years ago, not long after the first dinosaurs. Birds evolved from small carnivorous dinosaurs about 160 million years ago.
Yes, the first dinosaurs evolved in the Triassic period. The earliest dinosaurs that have been discovered are Eoraptor and Herrerasaurus, which lived 231.4 million years ago.
Dinosaurs evolved and then became extinct long before man walked the Earth.245 mya (million years ago) dinosaurs evolved.208 mya birds evolved.65 mya dinosaurs became extinct.80 thousand years ago humans evolved on the plains of Africa.
Scientists believe birds evolved from dinosaurs because of several pieces of evidence, such as shared skeletal features, fossil records of "transitional" bird-like dinosaurs, and genetic similarities. These connections suggest that birds are the descendants of a group of small theropod dinosaurs.
Fish, reptiles, and amphibians, originated in that order during the Paleozoic era.
