Cowboys vs Dinosaurs

In search of Iridium, a team of miners blast their way into a vast subterranean cavern in the small town of Livingston, Montana. But, instead of finding a rich source of the rare element, the unsuspecting crew comes face-to-face with hidden primaeval terror, as swift velociraptors emerge from the depths of the Earth, and start attacking them. Now, under the orders of the mine's greedy owner, Marcus, the workers need to get back to work, but, before long, a horde of scaly prehistoric predators turns the city into an endless buffet. Can Livingston's cowboys and cowgirls make the dinosaurs stay extinct?
