suprascapula, but many more primitive reptiles do.  It is _not_ the
coracoid; it is a separate ossification that occurs distal to the distal
end of the scapular blade.  The coracoid is located at the proximal end of
the scapula -- in primitive reptile pectoral orientations, it would be,
more or less, ventral and somewhat medial to the scapula; in dinosaurs, it
is proximoventromedial to the scapula.
