Neosqualodon is an extinct genus of toothed cetacean,[3] that lived in the modern Italy in the Middle Miocene (Langhian). Their fossils - mostly teeth and jaws - have been recovered in the Ragusa Formation of Sicilia, that are more robust and shorter than in the related genus Squalodon. Two species are known: N. assenzae and N. gemellaroi, that are distinguished by the shape of the teeth. Apparently this genus was endemic of the pre-Mediterranean sea of the Late Oligocene.[4]
