baby ptero ID

[david peters <davidrpeters@earthlink.net>]

In offline discussions with a DML member I gained new insight into the problems 
associated with entering juvies into a matrix. 

Still -- it will be necessary that all putative juvies show several 
synapopmorphies with putative adults of the same putative taxon in phalanx 
proportions, pelvis and prepubis shapes, and palate morphology before 
acceptance. It's not enough to say â?? or to say that Wellnhofer said â??  that 
one little taxon 'looks like' a short snouted, big-eyed, unfused version of a 
larger taxon. It could be phylogeny at work. 

The bar is raised.
