This is a GENUINE fossil Spinosaurus dinosaur tooth. This tooth is from a full-grown, adult Spinosaurus dinosaur and shows natural feeding wear on the tip and silicified sand still attached to the base.
The Spinosaurus dinosaur is estimated to have been THE LARGEST of all meat-eating dinosaurs that ever lived. With a length of 41 to 59 feet long, 20 feet high and weight estimates from 4 to 20+ tons, it was truly a behemoth! Spinosaurus was considered a bipedal dinosaur that is, one that walked on two feet although, its robust arms could have been used to allow the animal to walk on all fours at times. An extremely long snout was lined with an array of straight, conical teeth.
