TYPE LOCALITY . — Nihewan ( China ). AGE. — Late Pliocene; Haiyan Fm. correlative, early Matuyama. GEOGRAPHIC RANGE. — China , Mongolia , Transbaikalia. This is a relatively late Eucyon species known from the “Villafranchian” (Nihewanian) of China (the deposits from Nihewan of Teilhard de Chardin & Piveteau (1930) are correlative with the Haiyan Fm. of the Yushe Basin, dated by magnetostratigraphy to the early Matuyama; Flynn et al. 1991 ; R. H. Tedford pers. comm. in Rook 1993 ). Other specimens of E. cf. minor from the late Pliocene of Mongolia ( Rook 1993 ) are kept within the collections of the Institute of Geology in Moscow (GIN), from three Pliocene sites (MN 16, early Villafranchian; Pevzner et al. 1982 ; Vislobokova et al. 2001 ): Shamar, Beregovaja and Udunga ( Fig. 2 ). The specimen from Udunga has been described by Sotnikova & Kalmykov (1991) as Canis sp. The samples from Shamar and Beregovaja have been listed by Kurtén (1974) as coyote-like dogs. The lower carnassial morphology of the Shamar and Beregovaja specimens have the typical characteristics of the genus Eucyon . Rook (1993) , on the basis of dental morphology and the similarities with E. minor from China , attributed this material to E. cf. minor . More recently, Sotnikova (2004) proposed the same taxonomic placement for the larger of the two Shamar mandibles, but suggested an attribution to a new species for the smaller one. An attribution of the Shamar and Beregovaja specimens to E. cf. minor has been also suggested by R. H. Tedford (pers. comm. in Spassov & Rook 2007).
