Re: Early land tetrapods used dermal bone to counter CO2 in blood
Well, the paper is now online:
As a sidenote, I don't find this paper convincing. It includes many "predictions" that are
"confirmed" by "observations". But there is no attempt to analyse or to quantify the
variation of the parameters they discuss.
The fact that the last part of the discussion (focused on amniotes and relatives) is just worthless
does not help either. Seriously. Captorhinomorphs ? Polyphyletic. Romeriids ? *Romeria* is a
captorhinid. They could have meant members of the clade Romeriida instead of Romeriidae, but the
last name has been frequently used in the past so that it is very misleading (and given that the
cited reference is a paper published by Carroll on "romeriids", I think they just stuck
to the name included in the title - "Romeriidae" - and that was used in polyphyletic
sense). No dermal sculpturing in synapsids ? What about caseids ? And varanopids ? The more derived
eureptiles ? Aren't there a number of crocodylomorph having a sculptured skull ?
You might think I'm a bit harsh, but just read the paper and face the truth.

The paper is not posted yet on the Proceedings of the Royal Society B
website. Here are links to the press release and news stories about
the theory that bone helped neutralize acidity from CO2 in the blood
of early land-venturing tetrapods that had fixed ribs.
