Heloplax is a worm-like mollusc. Its soft parts are preserved in three dimensions in the Silurian Herefordshire lagerstatte; its disarticulated valves are known from other Silurian deposits.[1] It is very bizarre by modern standards; it bears serially repeated units, and has spines. It probably falls somewhere between the aplacophorans and polyplacophora; its valves were composed of aragonite[1]
