Three primary marine predators that shared the ocean waters of the Western Interior Seaway of North America 75 million years ago are illustrated here. Left to right is a non-descript invertebrate pursued by a 4 foot long Enchodus, followed by a 17 foot long Dolichorhynchops, followed by a 55 foot long Mosasaur.
