The present study on the molarspecimens of Villanyia,Rodentia,from the Renzidong Site shows that all specimens can beassigned to a single species of Villanyia,although some morphological variations do existamong these specimens.
经最近对啮齿目中维蓝尼鼠(Villanyia)化石的室内整理和研究表明,人字洞遗址出土的维蓝尼鼠臼齿标本之间虽然在形态上有明显的差异,但这些差异主要属于个体发育中的年龄差异,而不是种间筹异,因此这些标本属于同1个种。
