regarding the naris on pterodacs
Since Jaime brought this up...
shows my take on what appears to be happening on a very tiny, early
pterodactyloid, AMNH 1942. Perhaps the external naris was separate from the
antorbital fenestra in this case.
Crushing shifts elements and breaks thin bones. If there is a better
explanation for what is happening, of course I would embrace it.
The red arrow on the photo (courtesy of Chris Bennett's website) points to a
dendrite that I considered a tooth earlier. My mistake. Happens all the time.
The epipalatine labeled on the photo is a bone derived from the fusion of the
epipterygoid and palatine in basal pterosaurs.
