Sharks are fish. Since life got started in the oceans, fish had a long head start over land animals.

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).
Did primates evolve before dinosaurs became extinct?
no
Are cats older than dinosaurs?
No, dinosaurs existed before mammals. Reptiles and amphibians existed as long ago as 359.2 million years ago, while the first mammals didn't appear until 251 millions years ago.
Who appeared in fossils first dinosaurs or mammals?
Dinosaurs first appeared shortly before mammals did.
What came before the dinosaurs?
Fish, then amphibians then to reptiles then so on...
Were mammals around before dinosaurs?
Yes.
What came before the fish amphibians reptiles and dinosaurs?
Fish, reptiles, and amphibians, originated in that order during the Paleozoic era.
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 cave men live in dinosaurs?
No, cave men and dinosaurs did not coexist. Dinosaurs went extinct about 65 million years ago, while cave men, or early humans, appeared much later in history, around 2 million years ago. There is no evidence to suggest that they ever lived together.
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.
Were frogs around during the time of the dinosaurs?
Frog fossils have been found dating to the Jurassic period. The Jurassic period was the middle period in the middle of the Mesozoic. The Mesozoic was the era in which all dinosaurs lived, so frogs and dinosaurs did coexist.
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.
