Pseudoglyptodon

Pseudoglyptodon chilensis also known as Pseudoglyptodon is a fossil sloth which was found in the Tinguirirican (Palaeogene) from the Tinguiririca valley in the Cordillera Principal of the Chilean Andes. The species probably comes approximately from the transition from the Eocene and Oligocene. P.chilensis is known from a damaged skull with mandible and some damaged skull fragments. The species can differetiated from others based on a number of features: it is larger, has thinner teeth and less angled cusps on the molars. The discovery of this species lead researchers to the conclusion that the genus Pseudoglyptodon is the closest relative of the sloths depending on how the word "sloth" is defined.[1]
