Description and classification
The bones are fragmentary and represent roughly the elbow area. Comparing the fossils' size to the wing bones of other ground birds, P. barbarulna would have been relatively small, with a wingspan reaching 1 m (3.3 ft).[1]
The original description of the fossils found its affinities unresolvable except that it was probably an ornithothoracine bird. Agnolin and Varricchio (2012) reinterpreted Piksi barbarulna as a pterosaur rather than a bird, most likely a member of Ornithocheiroidea.[3] However, it has since been noted that the humerus of Piksi possesses features which found in some theropods but not in any pterodactyloid pterosaurs.[4]
However, more recent studies have recovered it as a pterosaur again.[1]
