I don't vouch for the accuracy of every news item posted, of course...


Maybe the real difference is here that the gastralia are actually
mounted on the MOR specimen. Were these found in place?  Sue's
gastralia are not mounted with the rest of skeleton, apparently
because of doubts about their placement.

 "See Sue’s gastralia, a group fossil bones so rare and unusual that
scientists aren’t sure how they fit onto Sue’s skeleton. Among the
most fragile of T. rex bones, they are most often incomplete, badly
damaged, or missing altogether from fossil finds."
