Introduced in the second Carnivores game, Spinosaurus as represented on the alien planet basically resembled a Baryonyx with a sail on its back (back then, nobody knew about its characteristic aquatic adaptations, but at least they got the elongated snout more or less right). It was depicted as similar to the Allosaurus in size, speed, and temperament, but required more points collected from hunting to unlock it as a prey item.
