Prioniodontida, also known as the "complex conodonts", is a large clade of conodonts that includes two major evolutionary grades; the Prioniodinina and the Ozarkodinina.[2] It includes many of the more famous conodonts, such as the giant ordovician Promissum (Prioniodinina) from the Soom Shale[3] and the Carboniferous specimens from the Granton Shrimp bed (Ozarkodinina).[4] They are euconodonts, in that their elements are composed of two layers; the crown and the basal body, and are assumed to be a clade[citation needed].
