21089 - Museum Grade Soft Bodied Aglaspid (Tremaglaspis unite) Lower Ordovician Fezouata Fm Palaeonotopterus Enchodus shumardiAglaspidida is an extinct order of aquatic arthropods that were once regarded as primitive chelicerates. However, anatomical comparisons demonstrate that the aglaspidids cannot be accommodated within the chelicerates, and that they lie instead within the Artiopoda, thus placing them closer to the trilobites. Aglaspidida contains the subgroups Aglaspididae and Tremaglaspididae, which are distinguished by the presence of acute spinose genal angles and a
