Foraminifera

I thought I would post some pics of what I am studying. Most people do not know what foraminifera are. So, by looking at the different species, there abundance, and distribution, I can determine how sea level has changed in the local marshes. If you take a pencil and draw the smallest dot you can on a piece of paper, that's about the size of 5 of these guys, the area I am working in has particularly small forams.
