Re: Pneumaticity in Triassic pterosaurs

Sharovipteryx has hollow leg bones and no one has looked for
peneumatic foramina in it. Opportunity missed. All other
fenestrasaur taxa are well crushed or 'impressionistic'.
Well, a lot of taxa have bones that look "hollow" in the sense of
being thin-walled, but were actually apneumatic and marrow-filled in
life. Archaeopteryx has quite a few long bone elements like this, for
example. Not that looking for pneumatic foramina would be a bad idea,
mind you. Just be careful describing the lower limb elements as
"hollow", as this implies a pneumatic element.
