摘要	Five taxa of Cervidae were identified from the new collection at Tuchengzi locality in Huade, Nei Mongol: Eostyloceros blainvillei, E. triangularis, Euprox sp.,Cervavitus huadeensis and C. shanxius, among which the first three taxa were discovered for the first time in Huade area, and the dental specimens of the last two taxa from Tuchengzi locality are also described for the first time. E. blainvillei is a large muntiacine, diagnosed by long, thick and medially curved main beam and a relatively long brow tine emerging directly from the burr. It was originally found in Yushe Basin in Shanxi Province, and reported later from Qaidam Basin in Qinghai Province. Huade is the third area yielding the species. E. triangularis distinguishes from E. blainvillei by its special main beam with triangular cross sections, and it was reported only from Yushe Basin. Its presence in Huade extended its geographic distribution northward to Nei Mongol. Euprox is a transitional form of cervids from permanent antlers to seasonally deciduous ones and it is found in several localities across Eurasia. Huade is the third area in Nei Mongol yielding the taxon after Tung Gur and Siziwang Qi (Siziwang Banner). C. huadeensis is a pliocervine with four tines, and particularly with two distal tines sword-like. It is found at Tuchengzi for the second time, but not elsewhere so far, and it seems to be an endemic taxon. C. shanxius distinguishes from C. novorossiae by absence of Palaeomeryx fold on lower molars. It is widely found in Shanxi, Shaanxi, Gansu and Nei Mongol of northern China. It is often found with numerous specimens in a locality that indicates it lived in large herds. E. blainvillei, E. triangularis and C. shanxius are main members of Yushe I, i.e. Mahui Formation or Baodean. Euprox appeared also mainly in the Late Miocene. The geological age of Tuchengzi locality based on excavated cervids is therefore the Late Miocene. The numerous specimens of C. shanxius indicates forested environment in Huade area in that age.
