A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
Velociraptor (veÂ·locÂ·iÂ·rapÂ·tor) (Speedy Thief) was a small carnivorous dinosaur, well known thanks to Jurassic Park. It was one of the smaller dromaeosaurs, smaller than Utahraptor and Deinonychus. It lived in Mongolia and China during the Late Cretaceous, 75 to 71 million years ago.
Fossilized bones were originally discovered in Mongolia. The Earth of the Cretaceous was similar to Earth as we know it today. The position of modern day Mongolia was the same as Mongolia of the late Cretaceous. Velociraptor was a terrestrial creature that lived in a dry desert with sand dunes.
