Pterosauria indet.

(Fig. 20 J-M)

DESCRIPTION

A third morphological group of pterosaurian teeth corresponds to slender, recurved crowns that are characterized by a subcircular cross section and poorly distinct carinae (Fig.20 J-M).The enamel is smooth whereas the basal part of the crown devoid of enamel (i.e., basal portion of labial and lingual faces) shows an irregular rugose texture.Teeth of this morphology can be observed in some non-pterodactyloid taxa(e.g.,the Late Jurassic rhamphorhynchid genus Bellubrunnus; Hone et al. 2012) and archaeopterodactyloids (e.g., ctenochasmatids; Perea et al. 2018); therefore, this third morphotype cannot be identified beyond Pterosauria indet.
