Computer models created by researchers at the Netherlands' Vrije Universiteit Amsterdam and Utrecht University-Vrije suggest the dinosaur Tyrannosaurus rex had a slow walking speed.

The scientists generated a three-dimensional simulation based on the skeleton of an adult female T. rex on display at the Dutch National Museum of Natural History.

The team digitally added muscles and organs, and permitted a suspension-bridge-like swaying of its tail.

Biomechanical analysis determined that the dinosaur would have preferred to walk at 4.6 kph (2.9 mph), which is close to adult humans' preferred walking speed of approximately 5 kph (3.1 mph).
