	Spinosaurus An eight ton theropod dinosaur of the genus Spinosaurus searches for its next meal 95 million years ago in shallow waters of what is today Egypt. With a massive crocodile-like head and enormous muscular body, this terrifying carnivore was larger than the Early Cretaceous Suchomimus and may have been mightier even than the famous Tyrannosaurus Rex of approximately the same period.
