Who appeared in fossils first dinosaurs or mammals?
Dinosaurs first appeared shortly before mammals did.
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.
What period is the age of the mammals?
Mammals first evolved during the Mesozoic, the age of dinosaurs. After the dinosaurs died out, the Cenozoic began and mammals diversified until they dominated the land. Currently, we still live in the Cenozoic, so, technically, the Cenozoic could be called "the age of mammals."
Are woolly mammoths older or younger than dinosaurs?
No. The first mammals appeared shortly after the first dinosaurs.
When did the first dinosaurs and mammals evolve?
The first dinosaurs AND the first mammals both appeared in the Triassic period From the Mesozoic era.
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.
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.
Did mammals or reptiles develop first?
reptiles because of the dinosaurs
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.
Where there mammals during the dinosaur age?
Yes. The first mammals appeared only about ten million years after the first dinosaurs in the Triassic period.
Which came first the woolly mammoth or dinosaurs?
Wolly mammoths came after dinosaurs.
What was the time when humans were existing with dinosaurs?
Humans never existed with the Dinosaurs. While the dinosaurs lived the largest mammals were about the size of modern rats and were mostly nocturnal (active while the dinosaurs slept). It was not until all of the dinosaurs had died that mammals could risk coming out of hiding during the daytime. The dinosaurs had been dead for about 10 million years before the first primates evolved, and humans evolved from primates about 54 million years after that (dinosaurs had been dead roughly 64 million years before the first humans lived).
