homoiostele

— Homoiosteles are superficially similar to stylophorans: the column or stele resembles the aulacophore and the theca in younger genera develope^([sic]) distinct marginal and somatic plate patterns. The earliest homoiosteles are attached by a holdfast, at least in juvenile stages, and this fixation may have imprinted some morphological features on steles of vagile genera. Earliest homoiosteles share significant characters with coeval species of the eocrinoid Gogia and it serves as outgroup.
