蛙嘴龙及其近亲为人类了解已有90年。
They were the size of swifts and until now it had been thought that, like swifts, they chasedaround the sky after insectsa technique known as hawking.
它们体型如雨燕般大小,直到今天,人们一直认为它们像雨燕一样在天空中到处疾飞追逐昆虫即一种被称为飞行捕食的摄食策略。
Dr Habib and Dr Witton believe this is wrong.
两位博士Habib 和Witton认为这种理论是错误的,
They suspect instead that Anurognathus sat in wait for its prey, and then sallied forth tointercept it like a surface-to-air missile.
他们猜想蛙嘴龙反而是静待猎物,然后像地空导弹一样突然腾空截击。
They came to this conclusion by comparing Anurognathus with 36 birds and 20 bats from theSmithsonian Institution in Washington, DC.
在将蛙嘴龙与取自斯密森学会博物馆的36种鸟和20种蝙蝠进行对比后,Habib和Witton做出这一推论。
Using a mix of computerised tomography and mundane measurements with callipers, theyassessed the lengths, widths, thicknesses, densities and bending potential of the bones ofthe modern animals and compared them with those gleaned from Anurognathus fossils.
他们综合了计算机断层摄影术和使用卡钳的普通测量方法,分析评估了现代动物骨骼的长度,宽度,厚度,密度及弯曲度可能性,并将它们和从蛙嘴龙化石中搜集到的数据进行对比。
