Oxysdonsaurus is an extinct genus of crocodylid crocodilian. Fossils have been found from the Paraná Basin in Argentina that date back to the Oligocene.[1][2] According to Edward Drinker Cope, the generic name is a misspelling of the intended name Oxyodontosaurus.[3] The genus is known only from a single tooth and is thus considered indeterminate.[4][5]
