When did Prehistoric animals and plants die out?

Answer 1

Ichthyosaurus was a marine reptile that lived during the Mesozoic, but not a dinosaur. The superficially fish-like reptiles died out in the Early Cretaceous, about 93 million years ago.

Answer 2

There have been many species of animals that have lived on Earth in the last few billion years. Certain species have become extinct, but, not all at the same time. Most dinosaurs became extinct hundreds of millions of years ago, after a meteor hit Mexico and spread debris over the Earth that changed the climate. The dodo became extinct about a hundred years ago, because humans like to hunt them until there were no more of them. Creatures that lived during the Ice Age, became extinct after the Ice Age ended. There is no one answer.
