Did dinosaurs exist at the same time as humans?
Inga [223]

No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.

This theory remains under discussion and shows that there is still much we don't know about dinosaurs.
