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. Paleontologist Nizar Ibrahim uses paleontological and geological data to reconstruct this “River of Giants” in surprising detail.
Travel way back in time to the Saharan desert to witness The ferocious predatory dinosaurs of Cretaceous Sahara, an animated lesson from TED-Ed.
Then learn more about the water-loving Spinosaurus in this National Geographic video.
