The name Ouranosaurus means "brave Lizard". It lived during the Early Cretaceous Period in Africa. It was named in 1976. The one who named this creature was french paleontologist Philippe Taquet. Like the carnivorous Spinosaurus, it had a sail on it's back, but surprisingly, Ouranosaurus was a herbivore. This iguanodont measured about 7 meters long and weighed about 4 tons. It belongs to a super-family called Hadrosauroidea, the group of the "Duck Billed Dinosaurs". As it was a herbivore in Early Cretaceous Africa, it was hunted down by many carnivores. It does not have weapons, so it probably ran away from a carnivore.
