Living in the tidal flats and channels of northern Africa Spinosaurus was likely an eater of fish although it may have scavenged carcasses if the opportunity arose. The long, narrow snout and the unserrated, straight teeth - 12 on each side of the upper jaw – are comparable to Irritator.

Noted for the long neural spines on its back which made it one of the largest theropods of the Cretaceous, the skin sail or hump may have been used for energy storage, courtship displays or regulation of heat.
