Abstract The Ilin cloud rat Crateromys paulus, identified from a single individual in 1981 and collected from an undocumented location in Ilin Island, Mindoro, Philippines, is now considered to be “data deficient” and possibly extinct. 96 murid dental fossil remains were recently recovered within a two-meter excavation of well stratified and chronometrically dated deposits at the archaeological sites of Bubog I and Bubog II on Ilin Island. Research on these well-preserved murid rodent remains confirms the past presence of C. paulus on Ilin Island and describes for the first time variability in dental morphology of this species. The succession of fossils within the detailed stratigraphic sequence also provides us with information on C. paulus throughout the Holocene and on its possible recent extinction.

来自民都洛岛伊林岛的已灭绝菲律宾云鼠 Crateromys paulus（Muridae：Murinae：Phloeomyini）的第一个化石证据，以及对其全新世丰度的见解

摘要 伊林云鼠 Crateromys paulus 于 1981 年从一个个体中发现，并从菲律宾民都洛岛伊林岛的一个无证地点收集，现在被认为“数据不足”，可能已经灭绝。最近，在伊林岛的 Bubog I 和 Bubog II 考古遗址中，在两米长的挖掘中发现了 96 件鼠齿化石遗骸。对这些保存完好的鼠类啮齿动物遗骸的研究证实了伊林岛过去曾存在 C. paulus，并首次描述了该物种牙齿形态的变异性。详细地层序列中的化石序列也为我们提供了关于整个全新世 C. paulus 及其最近可能灭绝的信息。
