It is the only Tyrannosaurus specimen alongside MOR 980 (Peck's Rex) in which the mount includes the real skull fossilized bones. [17] Also some of the actual gastralia or belly ribs were used, which had been found in articulation with the remainder of the ribcage, allowing for a particularly realistic restoration of the thorax.

This timeline of tyrannosaur research is a chronological listing of events in the history of paleontology focused on the tyrannosaurs, a group of predatory theropod dinosaurs that began as small, long-armed bird-like creatures with elaborate cranial ornamentation but achieved apex predator status during the Late Cretaceous as their arms shrank and ...
