These little stones are a real mystery, gamestones, perhaps?
The top stone in the column of three is a small meteorite.
Two sides of a paleo tool, a San Gabriel biface. The
top edge is the worked bit end.
Two more examples of fine scrapers, these uniface, but
with top edge as working bit end.
These are truly ancient tools.
Large bones such as this one, fit cleanly in the hand
and were frequently used as tools.
