Others have described the skull and neck to be possibly drepanosaurian in
nature. The skulls of drepanosaurids and _Longisquama_ are superficially
bird-like - which is why Senter (2004) gave the name "Avicephala" to the
clade containing Drepanosauridae and _Longisquama_.
[...] One researcher has been overheard remarking: "It
seems to be a fauna, not a taxon".
The neck, at least, is pretty obviously drepanosaurian -- either that or it
comes from a _highly derived_ bird (Ornithurae sensu strictissimo). I've
seen photos of the necks of *P.* and a drepanosaurid, and they're identical.
There's also theropod material in there; considering the fact that the lower
leg is much too big for the femur + pelvis, there must be at least 2
individual theropods in there (provided that one isn't, say, a
The foot, however, doesn't fit any of the above. It really looks birdlike,
and closer to the short-tailed birds than, say, *Archaeopteryx*. That said,
I should probably take another look at the small, bad photos... never trust
Chatterjee's drawings; they are always generous reconstructions.
