The known range of the Primates is extended down from the middle Paleocene to the early Paleocene and late Cretaceous by a new genus and two new species from Montana, Purgatorius unio and P. ceratops. These species approach condylarths and leptictid and erinaceoid insectivores in structure. Purgatorius is referred to a new subfamily, Purgatoriinae, of the Paromomyidae, but is probably not the stem primate. The fauna of Purgatory Hill indicates a late early Paleocene age.
蒙大拿州发现的一个新属以及两个新物种——尤尼俄普加托里猴（Purgatorius unio）和角面普加托里猴（P. ceratops），将灵长目动物已知的分布范围从古新世中期向下扩展到了古新世早期和白垩纪晚期。这些物种在结构上与踝节类动物、细齿兽类动物以及猬形食虫动物相近。普加托里猴被归入副鼠科的一个新亚科——普加托里猴亚科，但它可能并非灵长目动物的祖先。炼狱山的动物群表明其年代为古新世早期晚期。
