Excavated evidence suggests that, as well as being an active predator, the Tyrannosaurus was also an opportunistic scavenger, commandeering kills from smaller carnivores.
3. Bad posture
Tyrannosaurus rex was historically depicted with its body at 45 degrees or less from the vertical. This is not accurate, with a more horizontal posture likely.
4. Big foot
Two excavated fossilised footprints have been attributed to T-rex. The latest measures 83 centimetres (33 inches) in length and 71 centimetres (28 inches) wide.
5. Feathery young
According to a recent report in the journal Nature, Tyrannosaurus young may have been feathered for insulation, only losing their plumage in later years.
