What is this?

[Kevinrose.1]

Found while searching for cool rocks. New at this. Had a question answered yesterday. So figured id ask again. What this may be. Bout the size of a dime. Found in the yellowstone river. Was there looking for agates and possible sapphire? Again i dont really know much about rocks. But am curiouse if you folks can help identify.
