Data from: The first skeletal record of the enigmatic Cretaceous sawfish genus Ptychotrygon (Chondrichthyes, Batoidea) from the Turonian of Morocco
A new fossil batoid (ray) Ptychotrygon rostrispatula sp. nov. is described from five exceptionally well-preserved, three-dimensional skeletal remains from the Turonian (Late Cretaceous) of Morocco. These specimens represent the first known skeletal remains for the genus Ptychotrygon and allow an almost complete description of the genus providing a new insight to its phylogenetic relations and validate its taxonomic status as a member of the Sclerorhynchoidei. Mechanical preparation of the fossil remains revealed a relatively large batoid species (estimated total length beyond 1 meter). Overall morphology resembles that of sclerorhynchoids with a robust hypertrophied rostrum that lacks enlarged rostral denticles with enlarged paddle-like pectoral proximal elements (propterygium, mesopterygium and metapterygium). Never seen before details of the branchial skeleton are presented (large second hypobranchial without anterior process which was probably fused to the basibranchial and no evidence of articulation with other branchial element). To assess the phylogenetic relations of these specimens within the sclerorhynchoids a parsimonious analysis using TNT and PAUP software packages was performed. These analyses included Asflapristis cristadentis that along with Ptychotrygon rostrispatula sp. nov. were used as representatives of Ptychotrygonidae and also includes six other genera of sclerorhynchoids with relatively good skeletal remains. Both analyses recovered two monophyletic groups within sclerorhynchoids: the first contains Ischyrhiza, Onchopristis and Schizorhiza and a second that includes Micropristis, Sclerorhynchus, Libanopristis and Ptychotrygonidae.

FIGURE 9. Comparison of the rostral tooth shape of Pristis microdon and Pristis clavata from the Fitzroy River, illustrating the strong groove present along the posterior edge of the rostral teeth of P. microdon. This groove is present in (a) small juvenile (832 mm TL) and (c and e) larger juvenile (2271 mm TL) P. microdon, and runs the entire length of the tooth back into the rostrum itself. In comparison, the posterior edge of the rostral teeth of (b) small juvenile (865 mm TL) P. clavata is convex (lacking a groove), and although a groove may be present in (d and f) larger juveniles (2130 mm TL) it is rarely present along the entire length of the tooth.
