Let's fix those pterosaur eggshells! (was: ... pterosaur hands!)
Hey, that's fine. Keeps me in business.
In the tradition of science, all I wanted to do was reason through the
Along similar lines, I finally got to see Unwin and Deeming 2008
"Pterosaur eggshell structure and its implications for pterosaur
reproductive biology." All throughout the paper U&D reported on the
extreme thinness of the eggshell, its porosity and concluded several
times that it was most like that of non gekko squamates -- but they
couldn't pull the trigger and say that maybe pterosaurs were
squamates, as I suggested to Dr. Unwin in Sept. 2007. Instead they
opted to hypothetically bury the eggs in moist litter or soil. Nothing
was said, of course about each being a single egg (lotta work for one
egg), that one was buried in volcanic ash and two others in lacustrine
sediments (presumably having been transported there, but buried eggs
don't roll or float away in floods, do they?)
Ah, well. Maybe tomorrow.

I'm with Chris on this one. Decided he was right several year ago,
after detailed discussions with him. See no reason to change my mind.
