There's something strange about the Cleveland-Lloyd Dinosaur Quarry. The fossils found there date back to the Late Jurassic Period and one species accounts for roughly two-thirds of all the bones: Allosaurus fragilis. But what killed all these big predators? Was the site itself a deadly trap, like the La Brea Tar Pits? Or was it a poisoned spring? Or was it simply a watering hole? This episode will dig into the mystery of this dinosaur graveyard.
