The osteology of Prognathoglossum kalassyi, an osteoglossiform teleostean fish from the marine Cenomanian of En Nammoura in Lebanon, is described in details. This fish exhibits an important prognathism. The frontal is broad and short. The temporal fossa is located very laterally on the braincase. There is a small postfrontal behind the frontal. The parietal forms the dorsal border of the temporal fossa. The saccular-lagenar bulla is hypertrophied. This series of specialized characters is shared by the Recent osteoglossoid Pantodon and leads to range this Lebanese fossil genus within the family Pantodontidae.
