Description
You pronounce their name 'spin-oh-sore-us'. The meaning of Spinosaurus is 'Spine Lizard'. They were the largest carnivorous dinosaur. They lived in the Cretaceous Period. Their length was up to 50 feet. They weighed up to 20 tons (about 3 elephants!).

The Spinosaurus had powerful jaws with straight teeth. Most other meat eating dinosaurs have curved teeth. Scientists thinks this means they would shake their prey to tear off pieces. They lived in the Cretaceous period with all sorts of other huge Cretaceous dinos including T. Rex.
This dino had an amazing sail coming out of its back. The sail was made from spike shaped bones, joined together by a layer of skin. Scientists are not sure what the sail was for. It may have been used to control its body temperature. Skeletons have been found in North Africa.

There is still a lot of discussion among scientist about the true size of this huge dinosaur, as lots of estimates have to be made. Current figures say they weigh around 7000kg-20900kg (7 to 20.9 tons) and could grow 12.6 to 18 metres (41 to 59 feet) long. The skull alone was 1.75 meters long (5.7 feet). You can see that it could grow much bigger than a T. Rex. There were also a lot of other big dinosaurs around at the time - including the Giganotosaurus.
