Wukongopterus liiIVPP V15113 Early Cretaceous ~75 cm wingspan, was originally considered a strange sort of rhamphorhynchoid-grade pterosaur. Here Wukongopterus nests as a sister taxon to Darwinopterus and represents the last of this lineage. It is derived from a sister toKunpengopterus.
Distinct from Darwinopterus, the skull of Wukongopterus was deeper and less sharp anteriorly. The sacrum was relatively short. The caudals were slightly more robust.
The sternal complex was wider posteriorly. The scapula was longer. The posterior tuberosity of the humerus was longer. Fingers I-III were longer.
The pelvis was shorter. The ischium and prepubis were smaller. The tibia was more robust. The pes was larger with a more sharply bent p5.2 and longer unguals.
