What happened
Tyrannosaurus rex, one of the largest land predators of all time, lived in the final couple of million years of the dinosaur age in western North America. It reached around 12 metres long, had up to 60 teeth as long as 20 centimetres, and a bite several times more powerful than a lion's. The first skeleton was found in 1900 by Barnum Brown.
Why it matters
The apex predator of its ecosystem and among the very last non-bird dinosaurs, T. rex has become the most famous dinosaur of all.
