Spinosaurus is a carnivorous dinosaur that lived in what is now Northern Africa during the Cretaceous period—about 110 million years ago. Most scientist agree that this dinosaur probably hunted both on land and in water and probably lived on a diet of both fish and small mammals. It is believed these dinosaurs floated in much the same way that modern crocodiles do; lying in wait and then using the element of surprise to hunt prey. They were first discovered in 1912 in Western Egypt by Richard Markgraf, although this original specimen was destroyed during the bombing of Munich, Germany during World War II. Since then, scientists have had to make due with studying the plaster casts of this animal.
