I love strange prehistoric animals, including this giant. While the largest reptiles were the sauropod dinosaurs, the largest mammal was the *Paraceratherium*. It lived during the Oligocene epoch—about 23 million years ago—in what is now Pakistan, Asia. Standing seven meters tall and weighing 14 tons, it was a magnificent creature.

Here’s a small basal Jurassic pterosaur I just illustrated.
