Diet and environment of Mylodon darwinii based on pollen of a Late-Glacial coprolite from the Mylodon Cave in southern Chile
We studied the pollen content of a well-preserved coprolite of a Late-Glacial giant ground sloth (Mylodon darwinii) from the Mylodon Cave, province Última Esperanza, southern Chile. The specimen was obtained in 1909 and has been stored in a museum in the Netherlands since. It was radiocarbon dated t...
