was walking along. They later found a piece of the jaw with teeth still attached sticking out of the side of a hill. Today, about 65% of Scotty's bones have been recovered. A cast of Scotty was first to go on display at the T.rex Discovery Centre on March 15, 2013, followed by a second in an exhibit developed by the Australian Museum in November 2013. On March 21, 2019, Scotty was described to be the largest and oldest T. rex in the world, with an estimated weight of 8870 kg, length of 13.2 m and age of over 30 years. The previous owner of the 'longest lived T. rex' title was Sue, who lived to be 28. On May 17, 2019, a cast of Scotty was unveiled at the Royal Saskatchewan Museum.
