Today is International Sloth Day, apparently (Sloth Day is on the 19th, not, as NatGeo would have you believe, the 20th), so in honour of the occasion, here are abridged versions of four lesser-known (and one very famous) cryptozoological exploits through history relating to ground sloths. As we will see, ground sloths have had a very important place in palaeontological history. Most of these will eventually get their own blog entries.
