Onchopristis
Sign in to saveOnchopristis is an extinct genus of sclerorhynchoid, or sawskate, from the Cretaceous of North Africa, Europe, North America, and potentially South America. The genus 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. Specimens of Onchopristis have been discovered in coastal and fluvial deposits dated from the Barremian to the Cenomanian ages (~125-94 mya), making this genus one of the oldest known sclerorhynchoids.
