''Lonchidion'' is a genus of extinct
Hybodontiform shark in the family
Lonchidiidae. The genus first appears in the fossil record during the late Triassic and continues to be found until the late cretaceous.
Lonchidion was first described by R. Estes in 1964, and the type species is ''L. selachas''. Fossils of ''Lonchidion'' have been discovered across North America, Eurasia, India and northwest Africa in sediments representative of a variety of environments. A new species, ''L. ferganensis'', was described by Jan Fischer, Sebastian Voigt, Jörg W. Schneider, Michael Buchwitz and Silke Voigt in 2011, from fossilized teeth and
egg capsules.
