Re: Pneumaticity in Triassic pterosaurs

Interesting that they didn't even test the other option. 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.
