The ferocious predatory dinosaurs of Cretaceous Sahara

In Cretaceous times (around 100 million years ago), North Africa was home to a huge river system and a bizarre menagerie of giant prehistoric predators — including the Spinosaurus, a dinosaur even more fearsome than the Tyrannosaurus rex. Nizar Ibrahim uses paleontological and geological data to reconstruct this “River of Giants” in surprising detail.

Watch the ferocious predatory dinosaurs of Cretaceous Sahara from TED Ed. Then learn more about the water-loving Spinosaurus in this video from National Geographic.
