Question: What dinosaurs lived in which period?

Non-bird dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous.

What period did the dinosaur live in?

Are Sharks older than dinosaurs?

As a group, sharks have been around for at least 420 million years, meaning they have survived four of the “big five” mass extinctions. That makes them older than humanity, older than Mount Everest, older than dinosaurs, older even than trees. It is possible that sharks just got lucky in the lottery of life.
