Paracrinoidea - Springerocystidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|R. S. Bassler 1950||Like Columbocystis in general form but characterized by five relatively broad arms recumbent upon top of theca. Antanal side bears the strongly excentric base. Anal side very gibbous, especially toward lower end of theca, where it is angularly protuberant in a nearly horizontal direction. Plates much reduced in number and angulations connecting their centers correspondingly accentuated.|
