Your translation is correct but the suprascapular is not the coracoid
(which is below the scapula). The suprascapular is an extension of the
distal blade. It is usually cartilaginous. As far as I'm aware it rarely
if ever ossifies (but I suppose it could calcify which would lead to
its being preserved) I don't know if it is even present in Archosaurs, I
have observed it in Lizards and Frogs but not much else.
