Millericrinus sp. (D'Orbigny 1841)
4cm. wide. Holdfast with tube worm passengers which is attached to a piece of a Macrocephalites sp. ammonite. Epibionts attached to an epibiont. This root definitely attached itself long after the ammonite sank dead to the sea floor and broke its shell. An extremely rare find for the Wutach Formation. Herveyi zone, Callovian. Found in the Wutach Valley.
