In May 2019, a second mount was erected at the Royal Saskatchewan Museum in Regina, where the exhibit reflects the recent discoveries about the fossil.
[3][5][6] Although he was only there to learn how to find and identify fossils, Gebhardt uncovered a tooth and tail vertebra that the museum was able to verify belonged to a T.
[12] In 2010, the University of Alberta Department of Biological Sciences' Scott Pearson began work on a research project that sought to compare the sizes of known T. rex fossils.
[13] After prolonged study of the growth patterns in the bones, "Scotty" was also declared as one of the oldest known T. rex fossils at 30 years old.
The method used to calculate the mass in the latest study was the same for both of the specimens and the data shows that Scotty is heavier than Sue is.
A study conducted back in 2014 that estimated the weight for some of the large theropod dinosaurs and both Sue and Scotty were included.
Evolutionary expert John Hutchinson of the University of London's Royal Veterinary College has stated that the 5% margin separating SUE and Scotty is too close to rule out any error and that the difference most likely came down to inches and ounces, rather than the reported feet.
[19] The Chicago Field Museum's resident palaeontologist and curator of dinosaurs, Pete Macovicky, has stated that he believes Scotty and SUE are "statistically indistinguishable".
[18][22] Like other T. rex fossils, Scotty shows signs of trichomoniasis, a parasitic infection in the jaw that left visible holes in the bone and was unique to this specific species of dinosaur.
