Toes-first T. rex could outrun Usain Bolt, study suggests
A biomechanical analysis finds T. rex likely moved toe-first, similar to birds, enabling up to 20% faster speeds; a light 1.4-tonne T. rex could cover 100m in about 8.77 seconds, faster than Usain Bolt’s world record, with larger individuals still near 10.5 seconds.
