Bird and pterosaur palates compared

Short one today.
See figure 1 to compare primitive and derived bird and pterosaur palates. Lots of convergence! In each clade, one an archosaur, the other a lepidosaur, former tooth-bearing bones create a solid palate, meeting each other at the midline, as the rostrum comes to a sharp point, and the vomers gradually disappear.

Note:
these are cherry-picked taxa chosen for maximum disparity within their clade and maximum convergence between clades.

Earlier we looked at
the evolution of pterosaur palates in an 8-part series, ending here. Links there will lead you to the first seven parts. The evolution of bird palates is in process.
