Borealonectes is a genus of rhomaleosaurid pliosaur , a type of pliosaur that had a smaller head and longer neck than other larger pliosaurs such as Kronosaurus and Simolestes. The holotype fossils of Borealonectes were actually found within the Canadian Arctic, hence the name of the genus. Rhomaelosaurid pliosaurs like Borealonectes could be taken as in between the plesiosaurs and pliosaurs (though they are usually classed with pliosaurs), and may have had a greater tendency to tackle smaller prey than their larger pliosaurian relatives that were hyper carnivores of other large marine reptiles.
