Dinosaur - Velociraptor

During the Upper-Cretaceus period, about 70 million years ago the worldwas ruled by huge dinosaurs, such as Triceraptorses and Tyranosauruses. Many small dinosaurs existetd as well. One of these smaller dinosaurs was the veliciraptor, which means "a speedy predator".
Velociraptors were swifter and smarter then human and they were equipped with sharp teeth, large eyes and long clawed fingers and toes. Their most distinctive feature was a large sickle like claw as the second toe on each foot. These clawswere used to slashat their prey deadly wounding. Although Velociraptors weren't much bigger then human (about 2-3 meters in lengh), their strengh and ability to communicate with other raptors in pack were their the biggest assets.

We don't know exactly what have killed dinosaurs, but many scientist bealive it was a large comet or an asteroid that stucked cost of what is now the central America. There were other possibilities, such as a disease and climate changes that caused decline od the dinosaurs.
I think that extionction of dinosaurs benefited us people. If dinosaurs did not become extinct, mammals wouldn't have a chance to develop and would never become dominant land animals.
