re: Pterosaur pectoral girdles

Multiple origins for 1) notaria, 2) rotated scapulae and 3) scap
subequal to coracoid characters seem to be present in my studies, and
there seem to be no restrictions regarding size. As already discussed,
one can have a notarium associated with a fully rotated scapula and a
semi-rotated scapula. And there are a variety of notarial fusion
patterns present in the Pterosauria, as Chris has pointed out in
previous pubs.
