Arrow Heads

[Zook]

I found these arrow heads over the weekend on a friends property up around Gainseville FL. I am hoping someone can tell me a little bit about them. They are obviously made from 2 different types of stone but I was wondering what kind? Also is there anything that you can tell me about the design?

Thanks,
Mike
