History
In 1900, Stelleroidea was included as a class in F. A. Bather's echinoderm taxonomy, which grouped Asteroidea and Ophiuroidea within it as subclasses due to their Paleozoic history.<ref>Template:Harvnb</ref> In 1966, the Treatise on Invertebrate Paleontology included Stelleroidea as the only class within the subphylum Asterozoa, with Somasteroidea, Asteroidea, and Ophiuroidea as subclasses.<ref>Template:Harvnb</ref> By a 1980 revision of the Treatise's taxonomy, Asteroidea and Ophiuroidea had been promoted to classes in place of Stelleroidea.<ref>Template:Harvnb</ref>
