Obviously part of a sacrificial religious ritual. (Because it seems that every little piece of pottery they find is always part of a religious ritual. It sometimes seems that the ancients spent so much time performing religious rituals that they had no time for anything else)LOL! (I'm assuming that was sarcasm). My bet is that these people revered their young, as the best of us do. Grave offerings are not uncommon, and infants and premies have for much of history had a high mortality rate.
