Fossil Detectives and the Mysterious Skull

Dante and Lexy, young volunteers at the local Science Center, which recently acquired a prehistoric skull. But the skull has a hidden spirit which is awakened by an unexpected threat. It escapes with the kids back in time - not by a few years or even a few centuries, but millions of years ago. They would come face to face with dangerous predators that no modern human had even encountered, including the deadliest predator of them all, their own ancestors - the hominids.
