Imagine running through a great river valley. You're living a happy life and have much to eat. All of a sudden, mud buries you and everyone around you. Millions of years later, your bones are discovered by a group of scientists who then embark on a journey to figure out exactly what happened to you and your species.
In 1947, hundreds of the

This might be why the species is also believed to have been one of the most aggressive predators of all dinosaurs.
So, if their life was so easy, why did the
go extinct? Today, Ghost Ranch is a dry desert. Millions of years ago, however, it was a very wet valley. Scientists suggest that a great flood must have wiped out many of the dinosaurs in Ghost Ranch, including the
. During the supposed flood, mud and water would have buried and suffocated the dinosaurs quickly.
While scientists cannot be completely certain what killed the
