2007~2010年在云南昭通水塘坝砖厂采煤场进行的抢救性采掘中不仅出土了禄丰古猿新材料,使得云南的禄丰古猿产地新增了一处,而且还出土了一种麂的新材料。这种麂具有鹿角眉枝较低、主枝先向外侧偏上方向生长然后再向内侧弯曲,上臼齿具有发育的新棱和内齿带,四肢较短等特征。根据支序分析这种麂与元谋晚中新世雷老麂不是姐妹群关系,而是一个独立的支序,因此将新材料订立为一个新种:昭通麂(Muntiacus zhaotongensis sp.nov.)。1978年在昭通“永乐煤场”出土的“后麂(Metacervulus sp.)”也当归为昭通麂,而“永乐煤场”即为水塘坝煤场。根据古地磁地层对比的结果,昭通麂的出土层位均相当于C3An.1n,绝对年龄在6.1~5.9 Ma,为最晚中新世。
In 2007-2010, not only the new material of Lufeng ancient ape was excavated at the coal mining yard of Zhaotong Shuitangba Brick Factory in Yunnan Province, but a new addition was made to the origin of Lufeng’s ancient apes in Yunnan Province. Muntjac new material. This kind of deer has a lower deer hornbrush, the main branch to the outside of the first upward direction of growth and then bent to the inside, the molar with the development of new edges and internal teeth, short limbs and other characteristics. According to the sequence analysis, this muntjac is not a sibling group relationship with Yuanmou Late Miocene Ray Muji, but an independent order. Therefore, the new material was delineated as a new species: Muntiacus zhaotongensis sp.nov. Metaservulus sp. “Unearthed in Zhaotong” Yongle Coalfield “in 1978 also belonged to Zhaotong muntjac, while” Yongle Coalfield "was the shuntang coal yard. According to the results of palaeomagnetic stratigraphy comparison, the unearthed strata of the Zhaotong muntjac are all equivalent to C3An.1n with an absolute age of 6.1-5.9 Ma, the latest Miocene age.
