of the superior surface of the corpus and making its identification 

 more difficult). The first thoracic vertebra is preserved, and it articu- 

 lates poorly with this element, suggesting that this is the 6th cervical 

 vertebra. The inferior surface of the body is concave (not flat as is 

 normally found in 7th cervical vertebra: Bass, 1 987), and the anterior 

 tubercle of the transverse process is relatively large and thus looks to 

 be the carotid tubercle of C6. In addition, the end of the spinous
