Halisaurus is a comparatively small Mosasaur, maxing out at around 10 feet in length. It was a sleek and likely quick member of the family. Besides its small size, it had distinctive backward-curving teeth likely used for grasping slippery prey like fish. A paper describing this species can be found below.
