Pterodactylus scolopaciceps  BSP 1937 I 18 (Broili 1938, P. kochi No. 21 of Wellnhofer 1970, 1991) was a sister taxon in which the lacrimal process of the jugal was very low. A vomer ridge was medial to the maxillary teeth. The dentary was deeper. The teeth were fewer and relatively twice as large, as in No. 20. The ischium was rounder distally. The prepubis is strongly divided into a short anterior process and a very long ventral process, grealy deepening the torso.

The part (from Martin-Silverstone et al. 2020) and counterpart are known (see below). It is worthwhile to consider the possibility that the torso was much wider than tall, given the shape of the laterally-oriented ribs in situ. The family tree of the Pterosauria is here.

Pterodactylus sp.  MBR 3655 (Late Jurassic, Berlin specimen) has a large antorbital fenenstra, a large pectoral complex and a large prepubis. Related to P. scolapaciceps.
