Description
Original diagnosis after Adnet et al., 2020 [28754]: as for genus, Genus only known by isolated teeth with typical dasyatid design. Characterized by the presence of rugose crown marked by a sinuous transversal keel and secondary crests that tend to form an inner basin on the labial face. Cuspidate teeth have a small and thick cusp with a flat top extremity. The root could be high in anterior teeth with reduced rounded root lobes in lingual view.
