What is this?

I found this little rock digging around my house in Florida. Any idea what that is? Thx

Cool looking rock! Could be some type of chert?

That is some very high quality flint. I've never seen a source for that from FL...but who knows. Looks more like a piece of ballast flint from England than any US flint I'm familiar with. KY hornstone would probably be the closest look alike I know of. Gary
