Stegosaurus


Genus: Stegosaurus.
Classification: Ornithischia, Thyreophora, Stegosauride.
Length: 9m  Weight: 5000kg  Diet: Herbivorous
Period: Early Jurassic

The Stegosaurus had armour along their neck, backs and tails, in form of large triangular plates and spikes. They were four-legged, with hoof-like claws at the end of their toes. The most ancient Stegosaur was Huayangosaurus, which was about three metres in length, but Stegosaurus reached up to nine metres. At the beginning of the Creteceous Period, about 130 million years ago, these dinosaurs became extinct, possibly because of competition from new plant-eating species.

Triceratop

Genus: triceratops Classification: Ornithischia, Marginocephalia, Ceratopsia Length: 9m  Weight: 12 000kg  Diet: herbivorous Period: late Cretaceous Like all ceratopsians, Triceratops had a large outgrowth of bones at the back of the skull which protect the soft neck area. Research suggest that it used its horns as defensive weapons against predators, such as tyrannosaurus Rex. However, in dinosaurs such as Styracosaurus, they were only a few centimeters thick, so they wouldn't have been strong enouh to actually fight. Follow Tigers Super Sports on Facebook

Apatosaurus

Genus: Apatosaurus Classification: Saurichian, Sauropods, Diplodocoid Length: 27m  Weight: 35 tonnes  Diet: herbivorous period: Late Jurassic Apatosaurus is one of the most famous dinosaurs. At one time, it was called 'Brontosaurus' which means 'thunder lizard'. Perhaps because it is easy to imagine its heavy, rumbling steps, like thunder. Then it was discovered that the Brontosaurus and The Apatosaurus were really the same animal. Like all Diplodocoids, it was enormous, with a long whip-like tail, a long neck, small head and front legs are shorter than the rear. Tigers United : The Online Sports Magazine

Genus: Dilophosaurus Classification: Theropoda, Coelophysoidea Length: 6m  Weight: 500kg  Diet: Carnivorous Period: Early Jurassic Dilophosaurus was one of the largest coelophysoids, reaching up to 6m in length. Its name means 'two lophos (crest) reptile', since it most obvious characteristic was the complex structure of crests on its head. they were only few millimetres thick, and it is thought that they may have been used for communication and recognition, rather like cockerels use their fleshy 'combs' today.
