Question

Where does the dinosaurs go ?

Answer 1

$\bf\red{Answer}$

Dinosaurs thrived in the planet's consistently humid, tropical climate. But in the late Mesozoic Era that corresponds with the extinction of the dinosaurs, evidence shows that the planet slowly became cooler. Lower temperatures caused ice to form over the North and South poles and the oceans to become colder.

Answer 2

Answer:

Abundant fossil bones, teeth, trackways, and other hard evidence have revealed that Earth was the domain of the dinosaurs for at least 230 million years. But so far, not a single trace of dinosaur remains has been found in rocks younger than about 66 million years. At that point, as the Cretaceous period yielded to the Paleogene, it seems that all nonavian dinosaurs suddenly ceased to exist.
