Abstract: Four species of cricetid rodents are recognized and described from the upper Xianshuihe Formation of Tunggur age (middle Miocene) at Quantougou, Gansu. Among the cricetids, Ganocricetodon cheni is new. A comparison of the Quantougou assemblage with that of Tunggur reveals some suiking similarities in composition and obvious differences among cricetids, that are temporal, ecological, or both.

摘要： 记述了甘肃兰州永登泉头沟发现的4种仓鼠化石:Plesiodipus leei Young, 1927; Megacricetodon sinensis Qiu et al., 1981; Ganocricetodon cheni gen. et sp. nov.和Paracricetulus schaubi Young, 1927。仓鼠类的组合和形态特征表明:泉头沟动物群与通古尔动物群的时代接近，同属中中新世通古尔期;指示的环境近似，同为相对干旱的温带丛林—草原环境;但它们的时代和生态环境略有差异，不排除
