| 21. | The last paratype is the shoulder end of a left coracoid, catalog number PIN 4499-13.
|
| 22. | Specifically, the short head of the biceps originates from the coracoid process at the top of the scapula.
|
| 23. | The shoulder consists of the scapula ( shoulder blade ), coracoid, and humerus ( upper arm ).
|
| 24. | The epiphyses, carpal bones, coracoid process, medial border of the scapula, and acromion are still cartilaginous.
|
| 25. | The coracoid and carpometacarpus of the new species are larger and very different qualitatively from those of the Atiu species.
|
| 26. | A partial ornithurine coracoid bone found in this formation is identical to others found in the older Hell Creek Formation.
|
| 27. | The tendon of the short head runs adjacent to the tendon of the coracobrachialis and likewise attaches to the coracoid process.
|
| 28. | There is an obtuse angle between the scapula and coracoid, and the two bones fuse together to form a scapulocoracoid.
|
| 29. | Though the only remains are a coracoid and a humerus, these bones clearly identify it as part of the genus.
|
| 30. | It was named by Carpenter based upon a complete skull and lower jaws, neck vertebrae, and a right coracoid.
