Squalicorax (name meaning "Shark Raven"), commonly known as the Crow Shark, is a genus of lamniform shark that originated during the Late Cretaceous period in what is now North America, Europe, and Africa. Measuring almost 5 meters long and weighing a ton, this prehistoric shark was said to have similarities to modern gray reef and tiger sharks.
In the Series 2 finale "Death of a Dynasty: To Hell... And Back", a couple of Squalicorax were brought to the park from Late Cretaceous Montana, 65 million years ago. They reside in the Primeval Aquarium Enclosure.
