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.
|D. B. Blake 1994||Platanasterid with a large disk, relatively narrow ambulacrals, and broad adambulacrals; the channels for the radial and transverse water vascular canals are large and deep; podial basins are close to the arm axis and occupy nearly the full ambulacral width.|
|J. Dean Shackleton 2005||Axillary separated from marginal ring by pair of internal inferomarginals.|
