摘要
庙梁亚期代表着距今７～５Ｍａ期间的地质时期。可归这一正期的动物群有陕西府谷庙梁动物群、甘肃武都龙家沟动物群、河南新安各地点动物群、山西保德地区部分地点的动物群，以及榆社马会组所含动物群等。庙梁亚期动物群的组成已与保德早中期的有很大区别，其特征是鹿类大量出现并高度分异，三趾马以Ｈｉｐｐａｒｉｏｎｐｌａｌｙｏｄｕｓ为主，Ｃｈｉｌｏｔｈｅｒｉｕｍ基本不再出现。各地庙梁亚期动物群均是典型的森林型动物群，广泛分布在我国北部的山西、陕西、河南及甘肃等地。
The Miaolbog substage, which corresponds to the age interval of 7-5Ma,was defined by Xue Xiangxu et al.in 1995.The typical assemblage is Miaoliang Hipparion fauna found in Fugu County,Shaanxi. According to preliminary identification, the chief species of the fauna are Adcrocota eximia variabilis, Hipparion sp. Chilotherini,Honanotherium sp.Chleuastochoerus stehlini, Eostylocerus blainvillei,Muntiacus cf.lacustris, Cervavitus novorossiae,C.damissus, Procapreolus latifrons,etc.The faunas in this Substage include those found in Longjiagou, Gansu, at different localities of Xin'an, Henan, at some localities of the Baode area,in the Mahui Formation,Shanxi and in the Lantian Formation) Shanxi.The common features of the faunas are:(1) all faunas contain abundant fossils of Cervidae,such as Eostylocerus blainvillei,Muntiacus lacustris, Cervavitus novotossiae, C.demissus,Procapreolus latifrons,etc.(2) Acerorhinus is the dominant element of Rhinocerotidae and no fossils of real Chilotheerium have been found,(3) most animals of these faunas have low-crowned teeth,such as Honanotherium, Gazella g audryi and Chleuadechoerus stehlini,(4) Hipparion platyodus is the main species of hipparionine in this Substage.They were widely distributed in north China and most of these animals were typical forest dwellers.
