"Spinosaurus" bones were first discovered in Egypt in 1912 by German paleontologist Ernst Stromer in 1915. Two species, "S. aegyptiacus" and "S. marocannus", are recognized by many paleontologists, but there may only be one. "Spinosaurus" looked like "Baryonyx" except it was larger and more heavily built. Six specimens of "Spinosaurus" have been uncovered. Apparently, good material was destroyed in Munich in a 1944 bombing raid.
