| B. T. Kligman et al. 2025 | Nonpterodactyloid pterosaur diagnosed by the following unique combination of features found in the heterodont holotype dentary (the asterisk denotes autapomorphies): dentary teeth that are triangular in labiolingual profile, labiolingually compressed, tri-, penta-, hexa-,and heptacuspid, and often bearing fluting on the apical cusp*; two overlapping teeth followed by a short diastema in the anterior part of the dentary*; a large, recurved, monocuspid, conical tooth from a mesial position of the tooth row bearing fine apicobasal enamel striations*; extensive wear facets truncate the apices of nearly all erupted teeth*; some erupted tooth crowns ankylosed into sockets by mineralized tissue; medially open Meckelian groove becomes closed entirely within the dentary bone at the anterior terminus of the splenial facet; groove and adjacent ridge on lateral surface of dentary just ventral to the alveolar margin; dentary height lowest at its midpoint, forming an expanded anterior end. |
