1. Its functions are to move the scapulae and support the arm. 2. The scapulae will retract ( adduct ) during this type of fly. 3. Both the left and right scapulae and coracoids are known, though incomplete. 4. Muscles that retract the scapulae include the rhomboid muscle and the trapezius muscle. 5. Also, the scapulae of the examined specimens were identified to lack acromion processes. 6. Two coracoids are also preserved, although they differ more than the scapulae in morphology. 7. The scapulae are large, and robust, and thicken as they near the glenoids. 8. Plastrons do not become more numerous than scapulae until the R�nm�n ( �Nl ) Park phase. 9. Your shoulder blades are attached to the neck by the rhomboid, trapezius and levator scapulae muscles. 10. The grey mantle is 305 mm, and the scapulae are fringed brown, some tipped white.
