It's very doubtful that Spinosaurus lived in herds. One reason I say this is, because Spinosaurus was primarily a fish-eatter and a single river would probably not have enough fish to support a large number of Spinosaurus. The only time Spinosaurus would have lived together was during the mating season.
Richard Markgraf discovered the first partial Spinosaurus skeleton in 1912 in the Bahariya Formation of Egypt. This species is named Spinosaurus aegypticus. A second species, Spinosaurus moroccanus, was described by Dale Russell in 1996, but most paleontologists consider it a nomen dubium, or an invalid species.
