本文系统研究了产自广西扶绥岩亮洞与步氏巨猿下颌骨伴生的鼠亚科化石,包括：锡金小鼠（相似种）（Mus cf. M. pahari）、小巢鼠（Micromys minutus）、亚洲姬鼠（Apodemus asianicus）、细狨鼠（Hapalomys gracilis）、原始笔尾树鼠（Chiropodomys primitivus）、先社鼠（Niviventer preconfucianus）、安氏白腹鼠（Niviventer andersoni）、拟爱氏巨鼠（Leopoldamys edwardsioides）和始家鼠（相似种）（Rattus cf. R. pristinus）,共计8属9种,其中包括了6个绝灭种,鼠亚科绝灭种的比例高达67%。研究表明,岩亮洞鼠亚科动物群的性质比重庆巫山龙骨坡的相关鼠类显得稍进步,但比湖北建始龙骨洞以及广西崇左泊岳山巨猿洞和三合大洞的鼠亚科组合都要原始,因此推测其时代为早更新世早期（可能距今约200万年）。此外,依据主要属种的形态差异和演化水平,本文还初步建立了广西左江流域更新世鼠亚科动物群的层序,从早到晚依次为：扶绥岩亮洞（距今约200万年）—崇左泊岳山巨猿洞（距今约180万年）—崇左三合大洞（距今约160-120万年）—木榄山智人洞（距今约11万年）,这对于深入研究我国南方早更新世巨猿—中华乳齿象动物群的系统演化,以及探讨我国南方第四纪生物地层的划分具有积极的意义。

The new murid rodents associated with Gigantopithecus blacki from Yanliang Cave of Fusui, Guangxi Zhuang Autonomous Region of southern China are described in this paper, and include Mus cf. M. Pahari, Micromys minutus, Apodemus asianicus, Hapalomys gracilis, Chiropodomys primitivus, Niviventer preconfucianus, Niviventer andersoni, Leopoldamys edwardsioides and Rattus cf. R. pristinus. There are 8 genera and 9 species identified, of which 6 species (67%) are extinct. The combination of murid species from Yanliang Cave is more primitive than those from Longgudong Cave of Jianshi in Hubei, Sanhe Cave and Juyuan Cave of Boyue mountain in Guangxi, but slightly more advanced than that from Longgupo site of Wushan in Chongqing. The geological age of Yanliang Fauna is estimated to be the early Early Pleistocene (~2.0 Ma BP). In addition, the initial stratigraphic sequence (in chronological order) of the Pleistocene Murinae faunas from Zuojiang River watershed, South China is also proposed: Yanliang Fauna (~2.0 Ma BP) — Boyue Fauna (~1.8 Ma BP) — Sanhe Fauna (1.6-1.2 Ma BP) — Zhiren Fauna (~110 ka BP). The study on murid remains from Yanliang Cave, Guangxi greatly enriches the micro-mammalian record of the early Pleistocene Gigantopithecus-Sinomastodon fauna of southern China, and provides important evidence to understand the division of Quaternary biostratigraphy in southern China.
