The discovery of abundant skeletal remains of Felis trumani from a late Pleistocene deposit in Wyoming shows that it was as highly modified for cursorial locomotion as the cheetah (Acinonyx). Several other Pleistocene felids that have been regarded as pumas seem to be related forms. The late Pleistocene fauna of the Big Horn Basin in Wyoming is dominated by cursorial taxa.
在怀俄明州的一个晚更新世沉积物中发现了大量的穴狮骨骼遗骸,这表明它的奔跑运动适应性与猎豹(Acinonyx)一样高。其他几种被认为是美洲狮的更新世猫科动物似乎是相关的形式。怀俄明州大角盆地的晚更新世动物群以奔跑类群为主。
