Echinoidea - Diadematoida - Diadematidae

This is possibly a duplicate genus entry of Mesodiadema (taxon 32809) in Sepkoski's Compendium, but leaving them separate for now given widespread recognition in the literature (e.g., Smith, 2000; Kroh, 2011) that these forms are likely a different genus than the other forms.
