The Amazing Apatosaurus

This dinosaur is a prehistoric lizard,the Apatosaurus means "Deceptive lizard" it is the best known of all the long-necked plant-eating dinosaurs.It was around about in the late Jurassic,150 million years ago! The Apatosaurus walked on four legs and was a ornithisian (bird-hipped) dinosaur.

The Apatosaurus was a herbivore and ate gastroliths(stones) because it had peg-like teeth to snip off leaves. It ate things like herbs,twigs,leaves and many more. While they were walking the stones were grinding there food.

Apatosaurus was thought to keep it's tail off the ground when walking to keep it's balance. Each foot had short stubby toes on the front feet. The toe's of the back feet ended in claws. Each massive foot-print was up to 1 meter (3 feet) wide. Apatosaurus length was 21 meters and it's weight was 30 ton's.

The Apatosaurus lived in north America with some of it's relatives. The Apatosaurus stayed in a group called the theropod group.

Scientists believe that an astrode had hit earth which caused the dust to block the sun.Then the plant eaters would die because all the plants would die or the meat-eaters will eat them all.But then the Carnivores (meat-eaters) would die because they would die from starvation.
