Mitrates are an extinct group of echinoderms, which are grouped with the cornutes and the basal Ceratocystis to form the Stylophora. Mitrates were central to the now-disproven calcichordate hypothesis of chordate origins, but are now seen as either pre-radial-symmetry stem-group echinoderms, or as a derived group either within the blastozoans or near to the origin of crinoids.
