re: scapula question
...so...with primitive reptiles having a scapula that extends to the
spine, and with recent lizards having a short scapula, but with an
ossified extension that extends to the spine, the question remains -- is
this high old scapula with a sharp demarcation of transformation into
something new? or is it a novel addition on an old shrunken scapula?
Or did I ask the same question twice?
