It was just a hottie with a body.
lived during the Late Triassic and Cretaceous periods roughly 220 to 66 million years ago, was a much gentler giant than previously thought — despite the fact that it could grow up to 40 feet in length and had, well, terrifying three-foot-long claws"Therizinosaurus is famous for its sickle-like claws, each as long as a samurai sword: Edward Scissorhands on speed," study co-author Chun-Chi Liao, a paleontologist from the University of Bristol, said in aOf course, with a description...
But through a series of computer simulations based on 3D modeling, the researchers were shocked to discover that Therizinosaurus' terrifying talons were actually way too weak for combat. "Movies and documentaries suggest that they used these claws like long swords to fight each other or predators," Zichuan Qin, a doctoral student at the University of Bristol in England and leader of the study, told. "But our research suggests that they cannot bear any stress, which means these animals couldn't use their claws to fight or defend themselves.
"Not all therizinosaur hand claws were so useless in combat, but most other related species could use their claws as powerful hooking tools when feeding on leaves from the trees," Liao continued. "So we conclude the largest claws of any animal ever were actually useless in mechanical function, and so must have evolved under sexual selection to be used in display.
