Description
Original diagnosis after Adnet et al., 2020 [28754]: Mobulid-like taxon known only by isolated teeth. Dentition of supposed alternating rows with teeth weakly joined. The dentition comprises teeth more or less elongated with roughly hexagonal- shaped to teeth bearing a median keel expended lingually. The tooth crown is relatively low, slightly displaced lingually with a smooth labial visor, particularly pinched, and a lingual face that could be, at the contrary, strongly ornamented, with sinuous folds and grooves under the developed lingual keel. The occlusal face of the crown is strongly flat and smooth. The root is narrow compared to the crown, and bears irregular lobes with rounded bases, widely separated by deep furrows.
