Fossil group
Crinoids
Echinoderms · Ordovician – Recent
Stalked, flower-like echinoderms ("sea lilies") that filter food with feathery arms atop a stem of stacked calcite discs. Their broken stem ossicles are so common they form whole Palaeozoic limestones; stalkless relatives (feather stars) live today.
