Their burial customs.
The dead were buried with care and respect. Belief in immortality was expressed by placing material goods near the deceased to sustain him in the other world. His treasured belongings, usually pottery vessels, beads, bracelets and other ornaments, were buried with him.
The Moundville Indian built no burial mounds. His dead were buried in cemetery areas within the city. Usually burial was made in a pit large enough to accommodate the body at full length. Sometimes, however, burial was made in a small pit, the body being drawn up in a flexed position. Burial of the skeleton after it had been stripped of flesh was sometimes practiced.
