figurines often found with the head missing (several times they had detachable heads; stone figurines more often found with the head intact);
There was a deposit of a broken figurine-head in Building 17, placed directly over an earlier one (the head was also very similar to the earlier one, and both were different from other figurines found at the site);
Other clay figurines with a separate head were found in the first Area of the site. 
Figurines were deposited to "do" something (e.g. create links with the past) and found in domestic refuse context, often very small and easily/quickly made (low-fired or partially fired; clay lumps or unfired clay-balls could have been involved in figurine manufacture; figurines were made often and quickly as a part of daily practices).
