Asflapristis is an extinct genus of ptychotrygonid sclerorhynchoid that lived during the Late Cretaceous. It contains two valid species: A. cristadentis from the Akrabou Formation of Morocco and A. rugosa from the Eutaw Formation of Georgia and Mississippi and the Pleasant Creek Formation of North Carolina. Articulated skeletons of A. cristadentis show it had secondarily lost the rostral denticles typical of sclerorhynchoids, a process called "depristification".
