Spinosaurus was a large semi-aquatic dinosaur that is one of the main focuses of the documentary series Planet Dinosar.
Spinosaurus lived in Africa during the late Cretaceous Period. It's most striking feature is the large "sail" on its back that was connected to it's spine. The dinosaur was discovered to have been semi-aquatic suggesting it ate both fish and other dinosaurs although it prefered to eat fish. Like others of it's kind it hand claws which were capable of slahing it's prey but science suggest that they might have been shorter and walked on all fours.
The Spinosaurus appears in the first episode of Planet Dinosaur Lost World.
- The Spinosaurus was the first Spinosaurid to be openly known due to it's appearence in Jurassic Park 3 despite being a hybrid in the film.
