Interesting facts

Big Sue – Not only is Sue the largest and most complete Tyrannosaurus rex ever found, but Sue is also the oldest and most robust. Sue was 29 at the time of death. New research published by a team of scientists in 2004 revealed that as Sue aged, new layers of bone were deposited. The robustness of Sue’s bones is due to growth through a long life.

Tooth regeneration – Sue’s razor-sharp teeth regenerated throughout life. Look for Sue’s missing teeth as well as the ones that were still growing.

Skull holes – Scientists are still puzzled by the holes in Sue’s jaw. No new research has come to light on the function of these gaps.

Forearm theories – Scientists still don’t understand how T. rex used its powerfully built but short forearms. They speculate that T. rex used them in food acquisition, either through predation or scavenging, or possibly during mating.

Pathologies/Geriatric Sue – Fused vertebrae, broken ribs, extra bony growth. Sue was a mess. Scientists know that a big event happened to the right side of Sue’s body. There is damage to the right side of Sue’s skull, and right shoulder, and three broken ribs. The result of this damage is extra bony growth. Look for the growth on Sue’s ribs; it’s visible to the naked eye.
