| abstract | - When it came to be the last 20 million years of the Cretaceous, which brought the extinction of a few other marine predators, the Mosasaur became the dominant marine species. The Mosasaur was able to breath air, was a powerful swimmer, and were easily able to adapt to warm, shallow seas. Mosasaurs had a double-hinged jaw and a flexible skull, making them somewhat similar to modern day snakes. This helped them to easily gulp down their prey nearly whole. Size: The Mosasaur was typically about 3.0 metres (9.8 ft) to 3.5 metres (11 ft) long at its shortest. At its largest, around 17.5 metres (57 ft).

The discovery and study of mosasaurs near Maastricht in Europe in the late 1700s predated the finding of dinosaurs by more than fifty years. Many complete mosasaur specimens have been found in the Smoky Hill Chalk Member of the Niobrara Formation of Western Kansas, and some of the first mosasaur remains were collected by Professor Benjamin Mudge and Dr. George M. Sternberg more than 130 years ago. A few years later, in a series of scientific expeditions sponsored by O. C. Marsh and Yale University, hundreds of specimens were collected. As a group, the fossilized remains of mosasaurs had been found all over the world, from the west and mid-west of North America, South America, Australia and islands off the coast of Antarctica.
