I've seen plenty of Olmec ceramic figurines. Looks vaguely similar but without knowing which region it came from or how they ended up in the storage box there is really noway to know for sure.

This is a nice clay figurine that was made in the form of a human or animal. these where used to throw into the farm fields for offerings to the corn god. They are generally parts of pots or statues that where broken and saved for the spring time offering.
