《侏罗纪公园》系列电影给人们留下了这样一种印象,霸王龙(又称暴龙)能够全力冲刺地追逐猎物。但一项新的模拟研究显示,霸王龙其实并不擅长短跑,甚至都很难进行快步走。对这种重达9吨的恐龙来说,其最高速度约为每小时19千米。研究者指出,霸王龙的体型和重量使其无法跑动起来,并将运动速度限制在每秒5.4米(或每小时19.3千米)以下。如果运动速度高于这一速度,那霸王龙的腿骨就会无法承受巨大的体重而弯曲,甚 Jurassic Park series of films left the impression that Tyrannosaurus rex (also known as tyrannosaurus rex) can sprint enough to chase prey. However, a new simulation study shows that Tyrannosaurus Rex is actually not good at sprinting, and even difficult to walk fast. For a 9 tonne dinosaur, its top speed is about 19 kilometers an hour. The researchers pointed out that Tyrannosaurus size and weight so that it can not run up and limit the speed of movement of 5.4 meters per second (or 19.3 kilometers per hour) below. If the speed of movement is higher than this speed, that Tyrannosaurus’s leg bones will not be able to withstand the huge weight and bending, and even
