Hainosaurus (Haino from the river [[Haine]], where it was first discovered, and saurus, from Greek sauros, meaning lizard) is an extinct [[genus]] of marine [[lizard]] belonging to the [[mosasaur]] family. It is one of the largest mosasaurs, though its size has been revised more than once. At first it was estimated to be {{convert|17|m|ft}}, and the largest mosasaurid.<ref>Russell, D. A. 1967. Systematics and morphology of American mosasaurs (Reptilia, Sauria). Yale Univ. Bull 23:241. pp.</ref> During the 1990s, its size was revised to {{convert|15|m|ft}} long;<ref>Lingham-Soliar, T. 1998. Unusual death of a Cretaceous giant. Lethaia 31:308–310.</ref> more recently, Johan Lindgren estimated that it reached lengths of up to {{convert|12.2|m|ft}}.<ref>Johan Lindgren (2005) The first record of Hainosaurus (Reptilia: Mosasauridae) from Sweden. Journal of Paleontology: Vol. 79, No. 6, pp. 1157–1165</ref> It was one of the top marine predators of the [[Late Cretaceous]]. Like other giant mosasaurs, this giant predator preyed on [[turtle]]s, [[plesiosaur]]s, [[pterosaur]]s, [[cephalopod]]s, sharks, fish, and smaller [[mosasaurs]].
The fossils of H. pembinensis were found in the [[Campanian|Upper Cretaceous]] [[Pierre Shale]] in Manitoba, Canada in 1988. It was distinguished from Tylosaurus by having a greater number of vertebrae before the tail, a larger femur to humerus ratio, and larger nostrils. However, a 2008 study found that conclusion to be problematic, and thus reclassified into the genus Tylosaurus as T. pembinensis.<ref>{{cite journal|first=T. S.|last=Bullard|first2=M.
