What else can I help you with?
Who appeared in fossils first dinosaurs or mammals?
Dinosaurs first appeared shortly before mammals did.
Is it true that mammals cohabited with the dinosaurs?
Yes. Mammals were around through most of the time that dinosaurs were.
Were there other mammals with dinosaurs?
There were mammals living alongside the dinosaurs, but the dinosaurs were not mammals.
Did mammals appear in the fossil record before dinosaurs or after?
Mammals actually first came into existence about 220 million years ago, which is about 155 million years before the dinosaurs went extinct, and only about 10 million years after they themselves first evolved. So mammals actually lived alongside the dinosaurs, though played a much smaller role.
What came first a bee or a horse?
The bee came first, insects were around long before mammals or even dinosaurs.
What if dinosaurs were not extinct?
we and all large mammals would not be around
Where elephants here before dinosaurs?
Mammals did not evolve until dinosaurs were prolific when they did appear they were very small and very scarce when dinosaurs died out.
Did the mammals live before or after the dinosaurs?
The first mammals appeared in the Triassic Period of the Mesozoic Era, when dinosaurs had already been present for at least 9 million years.
Did mammals and dinosaurs ever shared the earth?
Yes, but the only mammals around at that time would have been small rodent-like mammals.
Who has lived longer on earth so far dinosaurs or mammals?
Mammals and dinosaurs started about the same time and mammals are still here, so ... Mammals! (Unless you count birds as dinosaurs, in which case it's a tie). One of the mysteries of evolution is why the dinosaurs came to dominate the mammals in the first place.
Which are older mammals or birds?
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.
Are dinosaurs the oldest mammals?
No. Dinosaurs were not mammals. They were more closely related to birds and modern reptiles than they were to mammals.
