“This research provides the first scientific evidence for hunting or scavenging of Ice Age sloth in North America,” said Redmond. “The significant age of the remains makes them the oldest evidence of prehistoric human activity in Ohio, occurring in the Late Pleistocene period.”
A series of 41 incisions appear on the animal’s left femur. Radiocarbon dating of the femur estimates its age to be between 13,435 to 13,738 years old. Microscopic analyses of the cut marks revealed that stone tools made the marks. The pattern and location of the incisions indicate the filleting of leg muscles. No traces of the use of modern, metal cutting tools were found, so the marks are not the result of damage incurred during their unearthing. Instead, the morphology of the marks reveals that they were made by sharp-edged stone flakes or blades.
