Re: Munich pterosaur symosium

The question of pteroid placement and configuration kept popping up. Those who supported the pteroid placement inside the bowl of the preaxial carpal where it could rotate anteriorly insisted that the pteroid fit in the bowl and when you play with uncrushed specimens (mostly Anhanguera) it rotates to certain spots readily. When Chris Bennett showed slide after slide of in-situ specimens from lotsa clades demonstrating that a pebble-like sesamoid always fits in the bowl of the preaxial carpal and the pteroid articulates lightly medial to it, oriented medially, no one from the opposing camp raised their hand in surrender.

Were those in-situ specimens uncrushed...?

Disclaimer: I have no opinion about the pteroid.
