Tyrannosaurus rex walked slower than you think, about 3 miles per hour
- Animal movement can be an important factor in determining ecological niche.
- Scientists assumed that animals reduce locomotor energy usage by doing gait movement tuned to the natural frequencies of related body parts.
- Researchers demonstrate that this allows them to estimate the preferred step frequency and walking speed of T-rex.
- The tail of dinosaur that walks in two legs was actively involve in walking.
- However, the tail was suspended passively by the caudal interspinous ligaments which allowed for energy storage through elasticity.
- To maintain high elastic energy storage, walking steps and natural frequencies would have to be complemented.
- Researchers determined the tail natural frequency to be 0.66 per second and the walking speed to be 1.28 meters per second.
- The walking speed in this study was found to be lower than earlier estimations for large theropods.
