Onchopristis is an extinct genus of sclerorhynchoid from the Cretaceous of North Africa, Europe, North America, and potentially South America.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.

The sawfish family has traditionally been considered the sole living member of the order Pristiformes, but recent authorities have generally subsumed it into Rhinopristiformes, an order that now includes the sawfish family, as well as families containing guitarfish, wedgefish, banjo rays and the like.
Sclerorhynchoidei is an extinct suborder of rajiform rays that had long rostra with large denticles similar to sawfishes and sawsharks.This feature was convergently evolved, recently proposed as 'pristification', [7] and their closest living relatives are actually skates.
Despite formerly being classified within a family of extinct sawfish-like rays known as Sclerorhynchidae, [4] phylogenetic analyses indicate that Ischyrhiza, Schizorhiza, and Onchopristis form a distinct clade that groups closer with the extant family Rajidae, which contains the true skates, possibly rendering the suborder Sclerorhynchoidei ...
