This huge T-Rex, nicknamed 'Scotty', roamed the Earth some 68 million years ago, and lived to the ripe old age of 28.
Life wasn't easy for him though, as it seems he survived many battles.. and has the scars to prove it.
Scientists actually discovered him more than 2 decades ago, but have been working since 1991 to uncover more of his bones, which were deeply embedded in rock.
