Squalodon is an extinct genus of whales endemic to Oligocene to Miocene, belonging to the family Squalodontidae. Named by Jean-Pierre Sylvestre de Grateloup in 1840, it was originally believed to be an iguanodontid dinosaur but has since been reclassified. The name Squalodon comes from Squalus, a genus of shark. As a result, its name means "shark tooth." Order: Artiodactyla, Infraorder: Cetacea, Superfamily: Platanistoidea, Family: †Squalodontidae.
