最近对墨西哥尤卡坦半岛东北部水下洞穴的古生物学研究发现了该地区多种多样的巨型动物组合,其中包括晚更新世巨爪科(Xenarthra)的地懒。本文报道了巨爪科一新种--Xibalbaonyx exinferisn。sp.,来自一个新的化石产地,名为托图加斯,位于金塔纳罗奥联邦州莫雷洛斯港以西。该分类群是基于一个片断的左下颌支,一个寰椎和一个左肱骨。新分类群的诊断是在短的联合喷口上有两个颏孔,一个犬齿是最小的下颌齿,Xibalbaonyx exinferisis是中国北方第三个特有的巨爪类动物,其分布于中国东北部,分布于中国东北部。东尤卡坦半岛,从而提供了越来越多的证据,该地区的生态隔离,从墨西哥的其余部分在更新世。
Recent palaeontological research in submerged caves of the north-eastern Yucatán Peninsula (YP) in Mexico has resulted in the identification of a diverse megafaunal assemblage in the area, among them Late Pleistocene ground sloths assigned to the family Megalonychidae (Xenarthra). Here we report on a new species of Megalonychidae,Xibalbaonyx exinferisn. sp., from a new fossil locality named cenote Tortugas, located west of Puerto Morelos in the federal state of Quintana Roo. The taxon is based on a fragmentary left mandibular ramus, an atlas, and a left humerus. The new taxon is diagnosed by the presence of two mental foramina on the short symphyseal spout, a caniniform being the smallest mandibular tooth, and the anterolaterally directed aperture of the mandibular foramen on the lateral surface of the mandible.Xibalbaonyx exinferisis the third endemic megalonychid documented for the north-eastern Yucatán Peninsula and thus provides increasing evidence for an ecological isolation of the area from the rest of Mexico during the Pleistocene.
