The Jurassic Period
Make sure you click on the Megalosaurs for a walking with dinosaurs video!!!!!!!!
Megalosaurus
Despite Megalosaurus being the first named dinosaur, very little is still known about it. No complete skeletons have ever been found and scientists have tried to work out its life style from that of other meat eaters. We know that it lived about 170 million years ago, at a time when the earths weather was mild. The world's plants were large and plentiful, as in a rainforest today. There were forest trees such as conifers, cycads and ginkgoes, and ferns and horse-tails grew on the ground. This scene would have been home to Megalosaurus, a predatory dinosaur that stalked through the vegatation in search of prey such as Iguanadon. But perhaps it was a scanvenger, too, eating flesh of dead animls like modern-day vultures.
Diplodocus
Diplodocus is one of the longest land animals that ever walked on the earth. as it moved slowly on its four trunk-like legs, it searched the landscape for food. This massive herbivore must have needed to eat a vast amount of vegitation to survive. When eating Diplodocus clamped its peg-like teeth around tall trees, then as it pulled backwards, its teeth tugged on the foliage and combed their way through it, stripping off a mouthful of food, which it swallowed whole. Once inside it stomach, gastroliths (stomach stones) rolled around knocking against the food, crushing it to pulp and making it easier to digest. Diplodocus may have lived in herd, travelling from one feeding place to another. It is one of the best known dinosaurs in the world.
Kentrosaurus
Kentrosaurus lived near river mouths. A plant eater, it spend most of its life wandering slowly across the floodplains looking for food, possibly in herds. It walked with its small head close to the ground, grazing on low-growing vegitation. As its hind legs were much longer than its front legs, it may have been able to rear up, balancing on its tail, to reach for plants that grew higher up.
Camarasaurus
Camarasaurus was a long-necked, long-tailed dinosaur that walked on all fours. It was one of the giant plant eaters of the late jurassic Period. Scientists beileive that while other plant eaters grazed on the soft, juicy parts of plants, Camarasaurus was able to eat the parts they didn't, such as twigs and branches.
Lesothosaurus
Lesothosaurus is one of the oldest african dinosaurs. It was a small lizard-like herbivore, about the size of a fox. it had a leightweight body, build for speed. It probably lived in packs, running swiftly across the,dry, hot and steamy plains of its homeland. As a herbivore it mostly ate low-growing plants, chewing on them with its sharp teeth. Some scientists think it may have eaten the occasional insect, or even carrion (meat from a dead animal) that it came across as it scratched on the ground. If Lesothosaurs sensed danger, it may have been able to signal to the rest of the pack by making a warning noise-and then, as quick as a flash, they would have scurried awy quickly to safety. A sudden burst of great speed was the main means of defense for this tiny dinosaur.
