摘要

在这里，我们回顾了地懒Nothrophus cararanensis Bordas的同型标本MACN Pv 12630，1942年，并提出它应该在分类学上重新定位到已灭绝的鹿Morenelaphus。该标本由一个零碎的脑壳代表，该脑壳与鹿科有几个共同特征，更详细地说，与Morenelaphus有几个特征。除了鹿角形态外，这一贡献表明，基本特征对阐明南美鹿科的分类亲缘关系也非常重要。

‘A Very Lazy Deer': Revision of the Cotype Of Nothropus carcaranensis (Mammalia, Xenarthra)

Here it is reviewed the specimen MACN-Pv 12630, the cotype of the ground-sloth Nothrophus cararanensis Bordas, 1942, and proposed that it should be taxonomically relocated to the extinct deer Morenelaphus. The specimen in question is represented by a fragmentary braincase, that shares several features with Cervidae and, more detailed with Morenelaphus. Besides antler morphology, this contribution shows that basicranium attributes are also very important to elucidate taxonomical affinities within South American Cervidae.

期刊介绍： Ameghiniana is a bimonthly journal that publishes original contributions on all disciplines related to paleontology, with a special focus on the paleontology of Gondwana and the biotic history of the southern hemisphere. Published yearly since 1957, it has undoubtedly become the main palaeontological publication from Latin America. Ameghiniana has recently broadened its editorial board, reorganized its production process, and increased to a bimonthly frequency, which resulted in a significant decrease in the turn around time.
