摘要: 本文记述了巨两栖犀属内的一个新种——马关巨两栖犀(Gigantamynodon maguanentisis)。它可能是两栖犀类动物中最大的一个种。其时代当为中、晚渐新世。

Abstract: Mr. Zhang Jiafa, a staff in the Cultural Museum of Maguan county, sent a piece of fossil mammalian maxilla with four cheek teeth (P3-M2) to IVPP in August of 1989. Having compared to other species of Gigantamynodon, I found that the specimen represented a new species in that genus. Its discovery locality is the south most one of the Paleogene mammalian localities of China. Apparently the specimen was collected from coal mine because it was surrounded by the coal. The age of the mammal is considered to be of Middle or Late Oligocene. It will be difficult for us to tell the further exact age because there is no other evidence.
