Athrodon

Athrodon is an extinct genus of marine pycnodontid fish that lived in shallow seas in what is now England, Germany, Spain and France from the Late Jurassic until the genus' extinction during the start of the late Cretaceous. The various species are very similar in splenial bone and tooth morphology to Mesodon. Otherwise, no articulated or complete specimen is known: all fossil specimens are bone fragments and disarticulated teeth. This genus is thought to be diagnosed by the presence of four lateral tooth rows. The presence of this genusin the Cretaceous is disputed, as the remains of Cretaceous species could belong to other genera.

The following species are known:
 * A. crassus Woodward, 1893
 * A. intermedius Woodward, 1893
 * A. jessoni Woodward, 1895
 * A. boloniensis Sauvage, 1880
 * A. profusidens (Cornuel, 1886)
 * A. tenuis Woodward, 1893
 * A. wittei (Sauvage, 1880)
