They also correctly observe that in the sclerenchyma of Monticuliporidae there are no \u201ccapillary tubes by which the walls of the Bryozoa seem always to be pierced in great numbers\u201d (p. 863), a statement apparently based on observations of some fenestrate Cryptostomata of the Salt Range, although only when describing <em>Thamniscus serialis<\/em> do they state that \u201cthe non-poriferous side is \u2026 pierced at intervals by very small pores\u201d (p. 810).<\/li>\n<\/ul>\n<p><em>Treatise on Invertebrate Paleontology, Part G (1953)<\/em><\/p>\n<ul>\n<li>Zoarium incrusting, ramouse, frondescent, bifoliate, or massive; generally with regularly spaced monticules. Zooecial tubes characterized by presence of incomplete curved partitions (cystiphragms) in addition to straight diaphragms; apertures polygonal. Acanthopores and angular mesopores with numerous diaphragms commonly present.<\/li>\n<\/ul>\n<p><em>Bassler (1911)<\/em>:<\/p>\n<ul>\n<li>The most important characteristic of this family, as emended by Ulrich, is the occurrence of the convex plates known as the cystiphragm.  These curved structures are limited to the zooecial tubes, where they form continuous series lining the walls.  In most of the genera the curve is complete, but in <em>Orbignyella<\/em> and <em>Mesotrypa<\/em> the cystiphragms are often so slightly curved that they have the appearance of being merely oblique diaphragms.  The use of the cystiphragms is not known, but it is possible that they represent ovicells.<\/li>\n<li>The method of zoarial growth in the family varies from incrusting through lamellate, massive, and ramose, to bifoliate, intertwining fronds.  It is noteworthy that the massive, free forms of <em>Prasopora<\/em>, the bifoliate forms <em>Peronopora<\/em>, and the delicate incrusting zoaria of <em>Atactoporella<\/em>, all of which are very abundant in certain faunas of the North American Ordovician, should be entirely absent in the Russian deposits.<\/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\"><em>Aspidopora<em><\/p>\n<p><a href=\"https:\/\/www.ordovicianatlas.org\/atlas\/bryozoa\/stenolaemata\/trepostomatida\/monticuliporidae\/aspidopora\/\"> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"https:\/\/i0.wp.com\/www.ordovicianatlas.org\/wp-content\/uploads\/2014\/07\/Aspidopora_eccentrica_250_black.png?resize=250%2C250&#038;ssl=1\" 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\"><em>Monticulipora<\/em><\/p>\n<p><a href=\"https:\/\/www.ordovicianatlas.org\/atlas\/bryozoa\/stenolaemata\/trepostomatida\/monticuliporidae\/monticulipora\/\"> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"https:\/\/i0.wp.com\/www.ordovicianatlas.org\/wp-content\/uploads\/2014\/08\/monticulipora-mammulata-250-black.png?resize=250%2C250&#038;ssl=1\" width=\"250\" height=\"250\" \/><br \/>\n<\/a><\/p>\n<\/div>\n<div style=\"float: left; width: 250px;\">\n<p align=\"center\"><em>Prasopora<em><\/p>\n<p><a href=\"https:\/\/www.ordovicianatlas.org\/atlas\/bryozoa\/stenolaemata\/trepostomatida\/monticuliporidae\/prasopora\/\"> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" alt=\"\" src=\"https:\/\/i0.wp.com\/www.ordovicianatlas.org\/wp-content\/uploads\/2014\/09\/prasopora-simulatrix-250-black.png?resize=250%2C250&#038;ssl=1\" width=\"250\" height=\"250\" \/><br \/>\n<\/a>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Classification Phylum: Bryozoa Class: Stenolaemata Order: Trepostomatida Family: Monticuliporidae (Nicholson, 1881) Cincinnatian Genera: Aspidopora, Monticulipora, Prasopora Geologic Range Ordovician &#8211; Devonian Common Paleoecology Monticuliporidae is an extinct family of colonial epifaunal suspension feeders Description of the Family Generally contains regularly-spaced &hellip;<\/p>\n<p class=\"read-more\"> <a class=\"more-link\" href=\"https:\/\/www.ordovicianatlas.org\/atlas\/bryozoa\/stenolaemata\/trepostomatida\/monticuliporidae\/\"> <span class=\"screen-reader-text\">Monticuliporidae<\/span> Read More &raquo;<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"parent":2203,"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-2457","page","type-page","status-publish","hentry"],"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/P3T22h-DD","_links":{"self":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/2457","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=2457"}],"version-history":[{"count":10,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/2457\/revisions"}],"predecessor-version":[{"id":12272,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/2457\/revisions\/12272"}],"up":[{"embeddable":true,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/2203"}],"wp:attachment":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/media?parent=2457"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
