TED-Ed: The ferocious predatory dinosaurs of Cretaceous Sahara - Nizar Ibrahim

The video explores the ancient Sahara Desert, which was once a lush river system during the mid-cretaceous period. This ecosystem supported a diverse range of predators and prey, including dinosaurs like Spinosaurus. Fossils from the Kem Kem Beds reveal how these creatures adapted to their environment. The video also discusses the mass extinction events that led to the rise of new species, including mammals and birds, paving the way for human evolution.

What role did aquatic prey species play in the survival of apex predators in the river system?

How did the mass extinction event affect the ecosystems that existed during the time of the dinosaurs?
