However, there are some factors that complicate a rhamphorhynchine position. In particular, the pear-shaped infratemporal fenestra and the overall size of the antorbital fenestra are more similar to scaphognathines than rhamphorhynchines. Additionally, like more basal non-rhamphorhynchid pterosaurs, there is a half moon-shaped process of the premaxilla extending beneath the nostril. It is thus possible that "Parapsicephalus" represents a basal rhamphorhynchid that is not in either group, which is not unexpected given its temporal context. The contemporary "Allkaruen" is also a potentially viable subject of comparison, although its material and that of "Parapsicephalus" do not readily overlap.
