This website is presented to showcase one of the most unusual Mississippian (early Carboniferous) fossils that occur in the midcontinent region of North America. The fossil, Evactinopora, a bryozoan colony, stands distinct because of its star-shaped form. It is most common in the Fern Glen Formation, which is a source of many fine fossils. The relationships and life habits of Evactinopora are of special interest because it lived free of attachment on the seafloor and made major changes in colony form during growth. This website is devoted to illustration and documentation of this fossil and to unraveling the tangled confusion in defining species of the genus.
