Here's more artifacts from a local private collection for your viewing pleasure. Anyone have idea on the clay cylinder in the drawn circle? I thought it was a pipe but it is only open on the top which looks like it broke off something. And the round stones?
The pottery or clay as you call it. My thoughts would be on it is a rattle head. They did make rattles out of pottery. My friend has a base of one but not the top.
On the round flat stones the 2 up top if aren't natural would be game pieces.
