河南卢氏盆地自李悦言(1938)发现哺乳动物化石后,周明镇(1957)在孟家坡一带采到大量晚始新世哺乳类化石,建立了卢氏组(层)。河南第四地质大队将卢氏盆地第三系自下而上分为卢氏组、何家沟组和大峪组。童永生、王景文于1979年在锄钩峪发现了晚始新世晚期的哺乳动物群,将卢氏盆地早第三纪地层分为卢氏组(包括十里铺组)、锄钩峪组和大峪组。新建锄钩峪组,其化石虽采自卢氏盆地之锄钩峪沟,但完整的地层剖面
After the discovery of mammalian fossils in Lushi Basin in Henan Province (1938), Zhouming Town (1957) collected large quantities of Late Pleistocene mammalian fossils in the Mengjiapo area and established the Lushi Formation (layer). Henan fourth geological brigade will be the third of the Lushi Basin bottom-up into the Lushi group, Hejiagou group and Dayu group. Tong Yongsheng and Wang Jingwen discovered the late Late Pleistocene mammalian assemblage in Hoe Hook Valley in 1979 and divided the Early Tertiary strata of Lushi Basin into Lushi Formation (including Shilipu Formation), Huxianyu Formation Valley group. New Hoe Hook Valley group, although the fossil from the Lushi Hook hook valley trench, but the integrity of the stratigraphic section
