      Hi @jkallmeyer – So this is a specimen that is commonly mistaken for a crinoid? Is that what you mean by pseudofossil? Thanks, Jen

        Perhaps pseudofossil isn’t a good choice. It is a pseudo trace fossil. Since trace fossils are those made by an animal doing something and this trace is made by water currents acting on a piece of crinoid stem I don’t think it can be called a trace fossil. Is that correct? This is not mistaken for a crinoid but might be mistaken for a real trace fossil.

          Okay, that makes more sense to me! You are correct, a trace fossil indicates animal behavior and this is nature acting on the (dead?) animal parts.
