Alien monsters? by: Doug These are some weird looking rocks! I don't know what you have here for sure but I will go out on a limb and guess that it could be upsidedown crinoids. There is some wear from the creek but it could be the caylex or aboral cup with the arms pointing down. Learn more about crinoids here: https://www.fossils-facts-and-finds.com/crinoids.html
