Named “Scotty,” the largest known T-Rex skeleton was unearthed in Saskatchewan, Canada in 1991. Its bones were encased in sandstone that was so hard it took about 10 years to finally clean and fully assemble all the bones that were found – even then it is still only about 65% complete.
Said to have roamed what is today Saskatchewan about 66 million years ago, it is said to be about 13 meters (42 feet) long! The previous record holder is a T-Rex named ‘Sue,’ is estimated to have weighed about 18,651 pounds and Scotty is estimated to have been about 5% heavier!
