| 1. | Its ankylosaurian affinities would be proven by a high acromion process.
|
| 2. | The acromion of the scapula rotates on the acromial end of the clavicle.
|
| 3. | They cushion and protect the rotator cuff from the bony arch of the acromion.
|
| 4. | Also, the scapulae of the examined specimens were identified to lack acromion processes.
|
| 5. | The greater / lesser tubercule are located from the top of the acromion laterally and inferiorly.
|
| 6. | When the rotator cuff tendon becomes inflamed and thickened, it may get trapped under the acromion.
|
| 7. | On plain film the inferior aspect of the clavicle will be above the superior aspect of the acromion.
|
| 8. | It is caused by a hyper abduction of the arm that forces the humeral head against the acromion.
|
| 9. | The scapula had a large rectangular acromion, with a sharp upper corner, on the lower front edge.
|
| 10. | Likewise, the oddly folded acromion is pointing ventrally and posteriorly, and not anteriorly as in other cetaceans.
