Tyrannosaurus Rex, one of the largest bipedal animals that ever evolved, was only limited to manage a walk, contrary to previous theories.
The running abilities of T-Rex have been a large topic of debate for decades now. In a study that was published in Peer J, a team from the University of Manchester, U.K., demonstrated how a T-Rex would move.
The research was based on a detailed computer model that used multibody system dynamics – which looks at connected solid objects – to analyse the bends and twists applied to different parts of a skeleton.
The findings suggest that the species would have suffered a broken leg if it even managed to move at a fast walk.
“We present a new approach that combines two separate biomechanical techniques to demonstrate that true running gaits would probably lead to unacceptably high skeletal loads in T-Rex”, said lead researcher William Sellers.
“So it represents a useful model for understanding the biomechanics of other similar animals. Therefore, these findings may well translate to other long-limbed giants so but this idea should be tested alongside experimental validation work on other bipedal species”, he further added.
