摘　　要：报道了甘肃临夏盆地具体产地未知的一件犬熊下颌。该下颌展现出进步的牙齿特征,与过去发现于欧洲以及南亚的马德里犬熊Magericyon近似。这件犬熊化石指示东亚的犬熊多样性比以往认知的更高,但还需要更多具有明确层位信息的犬熊化石来进一步揭示东亚犬熊的演化。Here we report a new form of amphicyonid from an uncertain locality in the Linxia Basin.The derived dental traits imply an affinity to Magericyon,previously known from Europe and possibly southern Asia.The specimen suggests a higher diversity of amphicyonids in eastern Asia than previously thought,and more discovery with stratigraphic information will be needed to elucidate the evolution of Amphicyonidae in eastern Asia.
