Actun Tunichil Muknal (the Cave of the Crystal Sepulchre) locally known as ATM is located in Belize. The cave became well known because of the skeletons, ceramics, and stoneware. The ceramics at the site are significant partly because they were used for ceremonial purposes. One of the best known skeletal remains is The Cyrstal Maiden, which is the skeleton of an adolescent girl who could have possibly been a sacrifice. The animal life in the cave includes a large population of bats, large fresh water crabs, crayfish, catfish and other tropical fish.
