Pterodactyloidea indet. A
( Fig. 20 View FIG A-D)
DESCRIPTION
This indeterminate pterodactyloid taxon is represented by small, labiolingually compressed teeth ( Fig. 20 View FIG A-D). The crown is relatively low, triangular and broad-based in labial and lingual views ( Fig. 20 View FIG A-C). The basal part of the labial and lingual faces is devoid of enamel, except along the mesial and distal carinae. The crown base is slightly inflated and the recurved apex is more or less slender, so that in labial view the carinae are convex and concave in the basal half and distal half of the crown,respectively. A weak enamel ornamentation consisting of faint vertical folds is present in some teeth. This taxon, characterized by a gradual heterodonty, corresponds to the morphotypes 5-7 reported from the Purbeckian beds of Chassiron ( Vullo et al. 2014: fig. 17eg) and to the isolated tooth MPZ2011/46 described from the Valanginian-Hauterivian of Pochancalo 1 in northeastern Spain ( Gasca et al. 2012:fig.3k).Since this tooth morphology is present in some archaeopterodactyloids (e.g., Pterodactylus , Germanodactylus ) and istiodactyliforms (e.g., Haopterus, Longchengopterus, Mimodactylus ) ( Lü et al. 2008; Wang et al. 2008; Kellner et al. 2019), we refer this taxon to Pterodactyloidea indet. A.
