That sounds a little ominous.  It's a discussion of phylogenetic taxonomy,

Ah well.  Looks like its fairwell Euhelopodidae then.  :-(

Yep, thanks; David M. pointed out _Barosaurus_ as well.  15 cervical and 10 
dorsal vertebrae are standard for diplodocids (Wilson 2005), but (among known 
diplodocids) _Barosaurus_ is exceptional in having 16 cervical and 9 dorsal 
vertebrae (your McIntosh ref).
