Update on new old bones

[Heather_Whitehead@MTS.RPI.EDU]

There is a new book due out soon devoted to 
Seismosurus and its discovery called
Seismosaurus The Earth Shaker (I think!). Its by
David Gillette, with illustrations by Mark Hallett.
My bookstore says June 1 for shipping date.
 
Ultrasaurus and Supersaurus were named for remains from
the Dry Mesa Quarry in Colorado,  mostly Jim Jensen's
work. To the bst of my knowledge, writeups on these are
fairly limited so far. I seem to recall discussion they may
represent large individuals of known species, but its still   
an open issue.
