Bromidechinus rimaporus Smith & Savill 2001 (topotype), 35 mm. Poolville Member, Bromide Formation, Dunn Quarry.

On the NHM echinoid site, Andrew Smith writes, "The plating structure in Bromidechinus is similar to that seen in ophiocistioids and Smith & Savill (2001) place this as the most primitive known echinoid."
