When Did Dinosaurs Extinct

Dinosaurs went extinct about 65 million years ago (at the quit of the Cretaceous Period), after dwelling on Earth for about 165 million years. If all of Earth time from the very beginning of the dinosaurs to these days had been compressed into 365 days (one calendar year), the dinosaurs seemed January 1 and grew to become extinct the third week of September. (Using this identical time scale, the Earth would have shaped approximately 18.5 years earlier.) Using the identical scale, people (Homo sapiens) have been on earth only in view that December 31 (New Year's eve). The dinosaurs' lengthy length of dominance really makes them unqualified successes in the records of lifestyles on Earth.

Dinosaurs lived on all of the continents. At the commencing of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents have been arranged collectively as a single supercontinent called Pangea. During the a hundred sixty five million years of dinosaur existence this supercontinent slowly broke apart. Its pieces then unfold across the world.

Did human beings and dinosaurs stay at the same time?

No! After the dinosaurs died out, almost sixty five million years exceeded earlier than people regarded on Earth. However, small mammals (including shrew-sized primates) had been alive at the time of the dinosaurs. Many scientists who study dinosaurs (vertebrate paleontologists) now assume that birds are direct descendants of one line of carnivorous dinosaurs, and some reflect under consideration on that they in fact signify current dwelling dinosaurs. This theory remains under dialogue and indicates that there is nevertheless a still much, we don't recognize about dinosaurs.
