Hi. I have a couple of questions.
I have an Australian book that states that a footprint genus
indicates that there possibly was a Tyrannosauroid on that
continent. Do you know anything about that?
I was also curious about a rumor I heard about T. rex skin
impressions having been discovered. Is that true?
My last question involves T. rex once again. Is the Jack
Horner-discovered "C-rex" larger than Giganotosaurus and the
other Carcharodontosaurines, or is it just a little smaller?
Thanks! Nice Book, by the way.

TOM: Thanks for the comments about the book.

Although the Aussie footprint was given a name that translates as "Tyrannosaurus-foot", there is absolutely NO evidence that it was from a tyrannosaur.

Although T. rex skin isn't known, there are some small patches of skin impressions (about the size of a playing card) from other tyrannosaurs. These show small bumpy scales (smaller than those of ornithischian dinosaurs of the same size).

Until we are given actual measurements of the "C-rex" specimen, we cannot know how big it is compared to previous discoveries. It might well be larger, but so far there are only preliminary news reports, not real scientific articles.
