However, none of the abundant and well-preserved limonitic molds of many species of <em>Fenestella<\/em>, <em>Polypora<\/em>, and <em>Archimedes<\/em> in Elias\u2019 collection have any trace of limonitic filling of the \u201ccapillaries\u201d.<\/li>\n<li>In view of all evidence and because of the erroneous implications connected with the terms, it seems advisable to discontinue to call the minute, (transverse to the laminated sclerenchyma) uprights in the wall of Fenestellidae \u201cpores\u201d or \u201ccapillaries\u201d. Instead, a term such as spicule or filament should be used (Fig. 1) which will denote that they are structural entities and not merely openings.<\/li>\n<li>From these considerations follows that in Fenestrata the neighboring zooecia share a common primary wall. This conclusion is at variance with the expressed belief by Ulrich that \u201cTheoretically it may be said that the zooecia of all the Paleozoic Bryozoa had perfectly independent and complete wall.\u201d Thus, the composite wall between two zooecia would be doubled, and the \u201cprimitive duplex character of the zooecial walls of the Fenestellidae and Acanthocladiidae is generally shown in deep tangential sections of the early stages of zoaria\u201d (Ulrich, 1890, p. 308, 312). No illustrations were published to support this observation , however, and it seems that it is the secondary sclerenchymatous crusts on both sides of the thin primary wall that correspond to what Ulrich called the \u201cprimitive duplex\u201d wall.<\/li>\n<li>In most species apertures are circular and are separated by about the distance of their diameter. Their size is commonly proportional to the size of the zooecial chamber, but in a few species they are unusually small in comparison with the chamber and are spaced more than their diameter apart. Outline and ornamentation of apertures, where preserved, are diagnostic. Bifurcation of branches is typically symmetrical; however, in a few exceptions there is a marked unilateral branching, rare in Fenestellidae and generally characteristic of <em>Septopora<\/em> and other genera of Acanthocladiidae.<\/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>Fenestella<\/em><\/p>\n<p><a href=\"https:\/\/www.ordovicianatlas.org\/atlas\/bryozoa\/stenolaemata\/fenestrida\/fenestellidae\/fenestella\/\"> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.ordovicianatlas.org\/wp-content\/uploads\/2015\/09\/fenestella-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<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Classification Phylum: Bryozoa Class: Stenolaemata Order: Fenestrida Family: Fenestellidae King, 1850 Cincinnatian genera: Fenestella Geologic Range Common Paleoecology Description of the Family [accordions title=&#8221;&#8221; disabled=&#8221;false&#8221; active=&#8221;1&#8243; autoheight=&#8221;false&#8221; collapsible=&#8221;true&#8221;] [accordion title=&#8221;Published Descriptions&#8221;] Elias &amp; Condra (1957): In all these examples, the &hellip;<\/p>\n<p class=\"read-more\"> <a class=\"more-link\" href=\"https:\/\/www.ordovicianatlas.org\/atlas\/bryozoa\/stenolaemata\/fenestrida\/fenestellidae\/\"> <span class=\"screen-reader-text\">Fenestellidae<\/span> Read More &raquo;<\/a><\/p>\n","protected":false},"author":4,"featured_media":0,"parent":2138,"menu_order":1,"comment_status":"closed","ping_status":"closed","template":"full-width-page.php","meta":{"jetpack_post_was_ever_published":false,"footnotes":""},"class_list":["post-12123","page","type-page","status-publish","hentry"],"jetpack_sharing_enabled":false,"jetpack_shortlink":"https:\/\/wp.me\/P3T22h-39x","_links":{"self":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/12123","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\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/comments?post=12123"}],"version-history":[{"count":10,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/12123\/revisions"}],"predecessor-version":[{"id":12562,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/12123\/revisions\/12562"}],"up":[{"embeddable":true,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/2138"}],"wp:attachment":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/media?parent=12123"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
