The Spinosaurus is a carnivorous dinosaur that lived in what is now North Africa during the Cretaceous Period, about 110 million years ago. Most scientists agree that this dinosaur probably hunted both on land and in water and probably lived on a diet of fish and small mammals. These dinosaurs are thought to have floated much like modern crocodiles do: they lay in wait and used the element of surprise to hunt their 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 settle for studying plaster casts of this animal.
The Spinosaurus is one of the largest dinosaurs known to scientists today. It is even larger than the T. Rex. In fact, a Spinosaurus weighs a ton more than a typical T. Rex and half a ton more than the next largest dinosaur, Gigantasauraus.
It was one of the first dinosaurs to have been identified as the first possible “swimming dinosaur.” It has a six-foot-long skull that was shaped like a modern crocodile skull. This made it easier for this dinosaur to catch fish.
These dinosaurs are thought to have walked on all fours when not in the water, but could also rear up on their hind legs like brown bears when they felt threatened.
They had a lot of different types of teeth. These included canines for tearing flesh, and an assortment of conical and crushing teeth. This was due to their varied diet that not only included fish, but may have also included small mammals and other dinosaurs.
