THE THEORY

Dr Stanley has based his theory on T-Rex's strong arm bones, which at a metre-long, 'were not as tiny as often portrayed.'

The dinosaur also had an 'unsual quasi-ball-and-socket-共同の', 許すing it to move its 武器 in several directions ? ideal for 削除するing, によれば Dr Stanley.

During its 進化, T-Rex also lost one of its three claws, resulting in 50 per cent more 圧力 適用するd by the remaining two, 供給するing a more powerful 削除する.

Dr Stanley 追加するd: 'In light of its formidable 兵器, why should T. rex not have engaged in this activity?'

Dr Steven Stanley, a palaeontologist at the University of Hawaii in Manoa argues that T-Rex's 武器 were more useful than thought.

Speaking at the 地質学の Society of America 会議／協議会 in Seattle, Dr Stanley said: 'Its short, strong forelimbs and large claws would have permitted T. rex, whether 機動力のある on a 犠牲者's 支援する or しっかり掴むing it with its jaws, to （打撃，刑罰などを）与える four gashes a metre [three feet] or more long and several centimetres [more than an インチ] 深い within a few seconds.

'And it could have repeated this 多重の times in 早い succession.'
