加拿大阿尔伯塔大学的考古团队经过长达数十年的重建骨骼历程，上周五（22日）终确认1991年在加拿大西部所发现的暴龙化石，是全球至今发现最大的暴龙。该只被取名为“史寇提”（Scotty）的暴龙身长13米，体重或超过8800公斤，超出所有过往发现的肉食性恐龙，研究人员更称之为“暴龙中的暴龙”。

研究的主导者、阿尔伯塔大学生物科学系的珀森斯表示，不同暴龙的体形之间可以有很大分野，有些比较瘦弱，有些比较强壮。据称，史寇提的骨骼在1991年被发现后，考古学家光是移除覆盖在骨头上的砂岩，就花了超过10年。

珀森斯与研究团队又认为，史寇提至少活到30多岁，在暴龙中算是长命一族，而且相信它每天都生活在暴力的弱肉强食世界中。研究指它的下颚有感染、肋骨骨折，且尾巴有部分伤势严重。
