Ctenoimbricata

Ctenoimbricata is an extinct genus of bilaterally symmetrical echinoderm, which lived during the early Middle Cambrian period of what is now Spain.^[1] It contains one species, Ctenoimbricata spinosa. It may be the most basal known echinoderm. It resembles the extinct ctenocystoids and cinctans, particularly the basal ctenocystoid Courtessolea. Ctenoimbricata is interpreted as a deposit-feeding pharyngeal basket feeder. It was relatively small, with a body 20 millimetres (0.79 in) long.
