CROW SHARK

The crow shark lived around the world 70–100 million years ago. The significance of the fossils of this species’ is not what has been found, but where they’ve been found. Nearly complete crow shark skeletons have been discovered in the land-locked areas of Wyoming, South Dakota, and Kansas, providing concrete evidence that the North American continent used to be divided in two by a midcontinental seaway connecting the Arctic Ocean to the Gulf of Mexico.
