Asflapristis
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".
