All fossils sold are authentic fossils, no replicas. Spinosaurus, genus of theropod dinosaurs belonging to the family Spinosauridae, known from incomplete North African fossils that date to Cenomanian times (roughly 100 to 94 million years ago). Spinosaurus, or “spined reptile,” was named for its “sail back” feature, created by tall vertebral spines. Spinosaurus, which was longer and heavier than Tyrannosaurus, is the largest known carnivorous dinosaur. It possessed a skull 1.75 meters (roughly 6 feet) long, a body length of 14–18 meters (46–59 feet), and an estimated mass of 12,000–20,000 kg (13–22 tons). Like other spinosaurids, Spinosaurus possessed a long narrow skull resembling that of a crocodile and nostrils near the eyes, instead of near the end of the snout. Its teeth were straight and conical, instead of curved and bladelike as in other theropods. All these features are adaptations for piscivory (that is, the consumption of fish). Other spinosaurids have been found with partially digested fish scales and the bones of other dinosaurs in their stomach regions, and spinosaurid teeth have been found embedded in pterosaur bones. The sail over the animal’s back was probably used for social displays or species recognition rather than for temperature regulation. Some authorities maintain that the sail was actually a hump used to store water and lipids. SP118
