Imbricata is a paraphyletic group of basal blastozoans that is traditionally considered to be an order. It is characterized by imbricate plating on some or all of the body wall, sharply delineated from the tesselate oral surface. This body organization is a plesiomorphic characteristic seen in other basal echinoderms such as Stromatocystites or Camptostroma.^[2] Imbricata contains the Lepidocystidae, which are the most basal group of blastozoans, and the Felbabkacystidae, which illustrate the transition to the Gogiida and other derived blastozoans.^[3]
