The food grooves are exothecal, i.e. are stretched out from the theca on jointed skeletal processes (brachioles). These either are close to the mouth or are removed from it upon a series of ambulacral or subambulacral plates not derived immediately from thecal plates, or are separated from the oral centre by hypothecal passages passing beneath tegminal plates. The stereom and stroma become arranged in folds and strands at right angles to the sutures of the thecal plates; in higher forms, the stereom-folds are in part specialised as pectini-rhombs.<\/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\">Dichoporita<\/p>\n<p><a href=\"https:\/\/www.ordovicianatlas.org\/atlas\/echinodermata\/rhombifera\/dichoporita\/\"> <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 style=\"border-right: 15px solid white; float: left; width: 250px;\">\n<p align=\"center\">Glyptocystitida<\/p>\n<p><a href=\"https:\/\/www.ordovicianatlas.org\/atlas\/echinodermata\/rhombifera\/glyptocystitida\/\"> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.ordovicianatlas.org\/wp-content\/uploads\/2014\/09\/cheirocystis-fultonensis-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","protected":false},"excerpt":{"rendered":"<p>Classification Phylum: Echinodermata Class: Rhombifera (Zittel, 1879) Cincinnatian Orders: Dichoporita, Glyptocystitida Geologic Range Early Ordovician &#8211; Late Devonian Common Paleoecology Rhombifera is an extinct class of stationary intermediate-level epifaunal suspension feeders Characteristics of the Class Thecal pores arranged in rhombs &hellip;<\/p>\n<p class=\"read-more\"> <a class=\"more-link\" href=\"https:\/\/www.ordovicianatlas.org\/atlas\/echinodermata\/rhombifera\/\"> <span class=\"screen-reader-text\">Rhombifera<\/span> Read More &raquo;<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"parent":2784,"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-4614","page","type-page","status-publish","hentry"],"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/P3T22h-1cq","_links":{"self":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/4614","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=4614"}],"version-history":[{"count":10,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/4614\/revisions"}],"predecessor-version":[{"id":13294,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/4614\/revisions\/13294"}],"up":[{"embeddable":true,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/2784"}],"wp:attachment":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/media?parent=4614"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
