Lestodon is an extinct genus of megafaunal ground sloth from South America during the Pleistocene period. Its fossil remains have been found in Argentina, Paraguay, Uruguay, and Bolivia. 4.6 m (15 ft) from snout to tail tip, it is estimated to have weighed between 2 and 4 tons. It was a herbivore and primarily fed on the grasses on the South American plains and is thought to perhaps have used its semi-bipedal stance to obtain foliage from trees.
