Mammals first appear in the fossil record of the Mesozoic Era.
In the Cenozoic Era, sometimes known as 'Age of Mammals' About 65 million years ago.
Many mammals appear on planet earth. Here are some of them:oxhumanpigmonkeycatdogfoxwolfantelopeelephantpolar bearhorse
The Jurassic. Mammals evolved continuously from the early synapsids of the Paleozoic to modern mammals, but the first mammals that are considered "true" mammals appeared in the Jurassic.
The first true mammals appeared during the late Triassic Period, about 200 million years ago.
The Cenozoic Era was when mammals first appeared on Earth!
The first dinosaurs AND the first mammals both appeared in the Triassic period From the Mesozoic era.
200 m.y.a. (million years ago)
they were the first dinosaurs on earth we think
Yes they did. They appeared about 10 million years before the first mammals.
250 b.c. .
The first true mammals appeared on Earth around 200 million years ago, in the late Triassic period. However, these mammals would remain small and relatively insignificant due to the dominance of the dinosaurs. Only when they died out 65 million years ago did mammals grow and diversify to become the ones we see today. The first modern humans (Homo sapiens sapiens) evolved around 200,000 years ago.
Dinosaurus were the first reptiles on earth.
The first mammals appeared during the Cretaceous Period.
I think when earth was cover in water.
the paleontogists believe that cathaymyrus was the first appear in the eon(on earth)
