Dinosaurs & Prehistory - Dinosaurs - Spinosaurus - Dinosaur anatomy - Predator-prey relationships
You are watching a Spinosaurus beside a vast river. Its long, narrow snout contains many cone-shaped teeth. What kind of prey was this set of teeth especially well suited to catch?
Correct!
Unlike the serrated, slicing teeth of many large predatory dinosaurs, Spinosaurus had comparatively smooth, cone-shaped teeth. Together with its long, narrow skull, they were well suited to gripping slippery prey. Spinosaurus probably often hunted large fish and other aquatic animals in rivers and along their banks.
Spinosaurus lived around 95 million years ago in what is now North Africa. Exactly how it moved through water and whether it actively hunted while diving remain subjects of scientific debate, but its strong association with water-rich habitats is well supported.
