Found this over ten years ago. I had a guy look it up
in one of his books, scholastic one I think, at a csas show.
Mine was associated with the Ohio River or Wabash River
system. Since I found it on the Tippecanoe River and it
connects with them. Don't remember the name, but yours
kinda resembles this. I'm thinking Woodland Era and it's
about 3.5 inches long.
