Dichoporites are characterized by a theca with endothecal pore-structures, and consisting of a reduced number of plates (usually 20-30), organized into three (hemicosmitids) or five rows (glyptocystitids). Their stem is well-differentiated, with a flexible proximal portion, and a more rigid, holomeric, distal region.<\/li>\n<li>Diploporita are blastozoan echinoderms characterized by exothecal pore-structures corresponding to diplopores (paired pores opening in a shallow depression) [Kesling, 1967; Paul, 1972a; Bockelie, 1984]. Diplopores are usually extensive and occur on most or all thecal plates. Most diploporites are characterized by a relatively globular theca, consisting of numerous (several tens to hundreds), unorganized, polygonal plates. A stem is sometimes present (e.g. <em>Destombesia<\/em>, <em>Eumorphocystis<\/em>), but it is absent in most forms [Kesling, 1967; Paul, 1972a; Bockelie, 1984; Chauvel, 1969]. Diploporites are usually subdivided into the four superfamilies Aristocystitida, Asteroblastida, Protocrinitida, and Sphaeronitida [Bockelie, 1984; Paul, 1984].<\/li>\n<\/ul>\n<p><em>Treatise on Invertebrate Paleontology, Part T, Vol. 2(1) (1978)<\/em>:<\/p>\n<ul>\n<li>Rhombifera with endothecal pore structures composed of dichopores and only developed across certain plate sutures; theca comprising a small number of plates arranged in 3 to 5 circlets; well-developed stem throughout life.<\/li>\n<\/ul>\n<p><em>Schuchert (1904)<\/em>:<\/p>\n<ul>\n<li>Dichoporita are Cystoidea whose thecal-pores are in pairs, each pair divided between two plates, situated vertically across the suture lines, slit or tubular-form, arranged parallel and combined into pore-rhombs, their ambulacral radial-grooves in special skeletal elements supported by the theca.<\/li>\n<\/ul>\n<p>[\/accordion] [\/accordions]<\/p>\n<div align=\"center\">\n<div style=\"height: 300px; width: 800px;\" align=\"center\">\n<div style=\"border-right: 15px solid white; float: left; width: 250px;\">\n<p align=\"center\">Callocystitidae<\/p>\n<p><a href=\"https:\/\/www.ordovicianatlas.org\/atlas\/echinodermata\/rhombifera\/dichoporita\/callocystitidae\/\"> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.ordovicianatlas.org\/wp-content\/uploads\/2014\/09\/lepadocystis-moorei-250-black.png?resize=250%2C250&#038;ssl=1\" alt=\"\" width=\"250\" height=\"250\" \/><br \/>\n<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Classification Phylum: Echinodermata Class: Rhombifera Order: Dichoporita Jaekel, 1899 Cincinnatian Families: Callocystitidae Geologic Range Lower Ordovician- Upper Devonian Common Paleoecology Dichoporita is an extinct order of stationary intermediate-level epifaunal suspension feeders Characteristics of the Order Thecal-pores are in pairs Pores &hellip;<\/p>\n<p class=\"read-more\"> <a class=\"more-link\" href=\"https:\/\/www.ordovicianatlas.org\/atlas\/echinodermata\/rhombifera\/dichoporita\/\"> <span class=\"screen-reader-text\">Dichoporita<\/span> Read More &raquo;<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"parent":4614,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"full-width-page.php","meta":{"jetpack_post_was_ever_published":false,"footnotes":""},"class_list":["post-4616","page","type-page","status-publish","hentry"],"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/P3T22h-1cs","_links":{"self":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/4616","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/comments?post=4616"}],"version-history":[{"count":10,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/4616\/revisions"}],"predecessor-version":[{"id":13296,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/4616\/revisions\/13296"}],"up":[{"embeddable":true,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/4614"}],"wp:attachment":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/media?parent=4616"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
