Sinopterus atavismus (Zhang et al. 2019; Early Cretaceous; IVPP V 23388) was originally considered a juvenile member of the Tapejaridae, but here nests as a small adult basal to Dsungaripteridae. The antorbital fenestra is not taller than the orbit. The carpals are no fused. No notarium is present. The antebrachium is robust. The distant pedal phalanges are longer than the proximal pedal phalanges. An internal egg appears to be present.

Dsungaripterus weii (Young 1964) ~4 m wingspan, Early Cretaceous was derived from a sister to Noripterus. Together these dsungaripterids represent the last of their lineage.

Distinct from Noripterus, the skull of Dsungaripterus was more robust with upturned jaw tips. Bone grew over the rear teeth during maturation. The suborbital region was further ossified. The mandible was more robust.

The sternal complex was rectangular. Posteriorly two sternal ribs (or gastralia) were massive. The gastralia were few and robust. The wing was more gracile.

The femur was more robust. The fibula was fused to the tibia.
