Order Calymenida


Calymemines had the highly lobed, furrowed glabella with eye stalks. They were distinguishable by the highy lobed body. Sometime, this group is classified as a suborder of Phacopida. Levi-Setti (1993) considers that they are more related to the Harpina and Trinucleida than Phacopida.
