sauropod necks-buckaroobwana is back! ha ha ha ha ha !!

[Buckaroobwana@aol.com]

This has probably been discussed before, but could sauropods raise their 
necks up into a vertical position? I have read that the structure of the 
vertebrae prohibits this, but it seems unlikely to me. Why is there do much 
doubt about the possibility of warm-blooded sauropods? It seems more 
plausible than either bulk endothermy or bulk homeothermy. Any response would 
be appreicated
