I was hiking the other day in southeastern Kentucky and ran across this rock on a river bank. I've never seen a rock like this before. Can anyone here identify it?

    Looks like a fossil coral (or something similar). What happens if you drop vinegar on it? Does it fizz?

    "on a river bank" is not very much. Do you have a more precise location? A description of the area? Photo's?

Your rock is most likely colonial horn coral fossil. It is common fossil in middle Devonian Period in Kentucky. I won't venture a guess on species from just an image. Kentucky Geological Survey has a nice introductory guide to fossil corals.
