What are these little green things?

while not an expert I've never seen anything like them before. Probably no one else has either. And since they were dug out of who knows where they could be from any time period or from any people who happened to be there at the time.

If they were from the Netherlands, don't they have laws about trading in antiquities? Which makes you wonder if they even are (ie, fakes).
