Paleontologist Nora Calder and a heavily armed corporate security team descend into a massive sealed subterranean world. They anticipate finding ancient trace fossils and silent geological wonders. Instead they are immediately thrust into a brutal Mesozoic ecosystem ruled by ferocious apex predators that hunt with terrifying intelligence.Trapped deep beneath the earth with their only exit compromised, the survivors must fight their way through a hostile jungle environment. Coordinated raptor packs stalk them from the shadows while an eight ton tyrannosaur adapts to their every defensive move. The underground ecosystem has spent eons perfecting the art of the kill. The human intruders must learn the ruthless rules of this uncharted domain immediately or become permanent additions to the bone field.
