Cincta is an extinct class of echinoderms that lived only in the Middle Cambrian epoch.[1] Homostelea is a junior synonym.[2] The classification of cinctans is controversial, but they are probably part of the echinoderm stem group.[1][3]
Cinctans were sessile, asymmetrical animals with a skeleton made of stereom plates and a racquet-shaped body composed of a theca and stele. They may have had a lifestyle similar to modern tunicates, filter-feeding by pumping water through gill slits in their pharynx.
