Aculeochrea Anabarites Cambrotubulus Mariochrea Selindeochrea

The anabaritids or angustiochreids are enigmatic tubular, mineralizing organisms with a trifold symmetry (i.e., clover shape) known from their Lower Cambrian fossils. They may have represented cnidaria, but their affinity within the Metazoa is difficult to constrain.^[1]
