Spinosaurus (meaning spine lizard) is a genus of theropod dinosaur that lived in what now is North Africa, during the lower Albian to lower Cenomanian stages of the Cretaceous period, about 112 to 97 million years ago.
1 Spinosaurus is the largest of all known meat-eating dinosaurs, even larger than Tyrannosaurus rex.  Spinosaurus is believed to have primarily fed on large fish. This is based on the elongated skull, spear-like teeth, location of the nostrils on the snout, and itâs habitat along the North African coast.
