A new record of a Scelidotheriine ground sloth (Xenarthra, Mylodontidae) from Central Brazil: Quaternary cave stratigraphy, taxonomy and stable isotopes
Abstract An upper fourth molariform of a Scelidotheriine ground sloth is reported from Carneiro Cave, which is located in the karstic region of Serra da Mesa (Goias). In this limestone cave the tooth was found at the base of a depositional sequence, associated with a 2 m thick debris flows deposit, which is covered by the lowest carbonate crust – dated at approximately 200,000 yr BP. Detailed morphological description, stable isotope data and stratigraphic context are provided. This represents the first megafauna record for this region of Central Brazil, where this record is found in direct association with a diverse microvertebrate fauna.
