Reinterpretation of the North American Strobilepis spinigera Clarke 1888 from the Devonian and the find of Diadeloplax paragrapsima gen. et sp. n. from the Pennsylvanian provide the basis for the recognition of a new class of uncertain affinity, Multiplacophora. The range of the class is Middle Devonian (Erian) to Pennsylvanian (Morrowan). Multiplacophora differ from the order Hercolepadida and the classes Thambetolepida and Polyplacophora in the number, shape, and arrangement of plates; the presence of large spines; and the complexity of internal canal systems in the plates and spines.

Turrilepadids are not uncommon in late Paleozoic shales being often associated with ostracodes, foraminifers, and minute molluscs. In North America they range from the late Missippian (Chesterian) to early Permian (Leonardian). Sclerites of the inner scleritome row are more common than outer sclerites. Some clusters have been found. Sclerite consists of two layers with the thicker, lower layer penetrated by a transverse tubular structures oriented perpendicular to the sclerite surface, which may represent canals related to the papillae on the inner surface of the sclerite. Turrilepas Lepros sp. n., T. trigoniodes sp. n., T. asketos sp. n., Clarkeolepis alloeospinosa sp. n., and Ambonlepidas petalos gen. et sp. n. are proposed.
