1978 年 4 月，在缅甸中部西北部 Mogaung 村西北约 1 英里的 Pondaung 山的始新世晚期，人们发现了一块含有第二和第三臼齿的灵长类下颌碎片。这个大约 40 年前的标本是自 50 多年前发现有争议的最早类人猿 Pondaungia cotteri Pilgrim1 和 Ampithecus mogaungensis Colbert2 的碎片遗骸以来，在缅甸发现的第一个灵长类动物化石。这里描述的下颌被认为代表了 P. cotteri 的进一步证据。毫无疑问，它是从始新世晚期暴露中恢复的，加上其显着的高等灵长类特征和良好的保存状态，为进一步证实缅甸的庞当灵长类动物是已知最早的类人猿记录提供了机会。
In April 1978, a fragment of a primate lower jaw containing the second and third molar teeth was found in late Eocene exposures of the Pondaung Hills about 1 mile north-west of Mogaung village in northwestern Central Burma. This approximately 40-Myr-old specimen is the first fossil primate found in Burma since the fragmentary remains of the controversial earliest anthropoids Pondaungia cotteri Pilgrim1 and Ampithecus mogaungensis Colbert2 were recovered more than 50 yr ago. The jaw described here is believed to represent further evidence of P. cotteri. Its recovery from undoubted late Eocene exposures coupled with its salient higher primate characters and excellent state of preservation provides the opportunity to substantiate further that the Pondaung primates of Burma are the earliest known record of the Anthropoidea.
