My portrait of the largest and best-preserved Tyrannosaurus rex specimen found thus far, the one called FMNH PR 2081 (better known as "Sue"). In life the dinosaur would have caught a bad case of Trichomonas gallinae, the scars of which remain on their skull. Not to mention numerous other injuries (e.g. broken ribs, a torn tendon on the right arm, and a damaged shoulder blade) and pathologies obtained from a violent predatory lifestyle. Sue would have been approximately 28 years old by the time of death, which is old as far as T. rex specimens go.
