Hainosaurus ( after the river groves ) is a genus of mosasaur from the Upper Cretaceous time.

Three species have been described: H. bernardi whose fossil remains were found in Belgium, H. pembinensis from the early Campanian of Manitoba and Hainosaurus gaudryi from the Santonian of France. A 65- million year old, only partially preserved skull, which was found on the island of Seymour east of the northern tip of the Antarctic Peninsula could come from Hainosaurus or his close relatives Tylosaurus.

Features

Hainosaurus was hoffmannii next mosasaurus one of the largest mosasaurs and could be 12 to 17 feet long. He had an elongated body and of all the mosasaurs he had with 53 most Präcaudalwirbel (all vertebrae except those of the tail (Latin cauda ) ), Tylosaurus had 35 Hainosaurus but had a shorter tail than Tylosaurus with fewer tail vertebrae.

The 1.5 -meter-long skull was shaped like an arrowhead and a reinforced toothless rostrum. He could possibly be used to prey or rivals to kill by ramming or to incapacitate, similar to dolphins in the fight against sharks. At the Institute Royal des Sciences Naturelles de Belgique is a fossil of mosasaur hoffmannii whose skull was crushed by a strong shock. The teeth of Hainosaurus were sawed. In the stomach of a specimen was found turtles parts.
