variable scap/cora in pteros

[David Peters <davidrpeters@earthlink.net>]

With the likely shifting of the center of gravity in pterosaurs due to a
variable anterior mass moment (the skull on the end of a swinging
cervical series), I was wondering if a scapulocoracoid that pivoted at a
medial axis (the notarium or its non-notarial equivalent) would solve
this problem without affecting the rest  of the wing's engineering. Sort
of like a swing-wing fighter. The opposing trapezius and latisimus dorsi
muscles appear to have been massive enough for the job.

This could easily have evolved after pterosaur wings appeared because
the most primitive pterosaur, MPUM 6009, has a very short cervical
series, hence no factor.

Any thoughts?

Also I'm wondering if what those are tiny teeth I think I'm seeing in
