dinosaur speed

Dinosaur speed estimates come from tracks, bones, muscle models, and biomechanics. This guide explains what scientists can and cannot know.

T. rex is not just a cultural icon — it is the most scientifically studied non-avian dinosaur in history, with over 50 reasonably complete specimens and a research record spanning more than a century. What emerges from that scrutiny is more complex and more surprising than the movie monster: an animal with the most powerful bite force ever measured in a land animal, better depth perception than a hawk, and a growth strategy that turned a 50-kg juvenile into a 9-tonne adult in roughly 20 years.
