Question

There are no dinosaurs roaming on the earth now. Do you know why?

Answer 1

We don’t know why most dinosaur species are extinct. That’s because the dinosaur timespan ranged over about 170 million years. It’s an easy figure to type, but almost impossible to truly understand. It’s long enough that the entire “age of mammals” could fit within the “age of dinosaurs” about two and a half times, and during this time dinosaurs were present the world over. Species came and went as evolution spun off new variations and extinction eventually picked them off, and, unfortunately, the fossil record doesn’t offer enough resolution to pinpoint why this or that species eventually vanished.
