drawings of Quetz in the _Encyclopdeia of Pterosaurs_>
On the contrary, *Q.* sp. has a flexible neck,
capable of quite some dorsoventral flexure. There may
have also been a great deal of rotation inate in the
cerviocranial joint (occipital condyle and atlas), and
for a six-foot head, this may have been quite
significant. Okay, there's an if. The study's not out
yet. No study has been made of Quetz' neck, so
Sibbick's painting is hypothetical, rather than based
on fact. I guess storks and other long-necked birds
were the basis of the restoration, but that's a guess.

Dinosaurs are horrible, terrible creatures! Even the
fluffy ones, the snuggle-up-at-night-with ones. You think
they're fun and sweet, but watch out for that stray tail
spike! Down, gaston, down, boy! No, not on top of Momma!
