Onchopristis is an extinct genus of sclerorhynchoid from the Cretaceous of North Africa, Europe, and North America. Its name is derived from the Ancient Greek ónkos (ὄγκος, 'barb') and prístis (πρίστις, 'saw' or 'sawfish').[2] It contains two valid species, O. numida and O. dunklei, though some researchers argue that both may be considered a single taxon with variation in morphology caused by a wide geographical range.[12] Specimens of Onchopristis have been discovered in coastal and fluvial deposits dated from the Barremian to the Maastrichtian age,[13] making this genus one of the oldest and longest-lived sclerorhynchoid genera.
