Harlan’s Ground Sloth, Glossotherium harlani, was the largest and most common sloth from Rancho La Brea. It had bony nodules embedded in its skin which probably acted as armor in defense against predators. At least seventy-six of these animals have been found in the pits so far. Ground sloths originated in South America and spread into southern North America about two million years ago. Follow the blue line below for the approximate time of its extinction.
