The primary shell is composed of three layers consisting of the initial, subsequent and final layers. The early ontogenic parts have two different modes of construction (Fig. 14): The first begins with differentiated larval parts, closed at the apical end, showing a distinct biologic metamorphosis; alternately, the cone passes through an embryonic stage with no obvious postembryonic differentiation. Transverse or\/and longitudinal sculpture are present, and secondary shell, pseudopuncta and septa are sometimes present.

The tubes are usually straight, but sometimes slightly curve, or in some cases they are attached to foreign bodies-even irregular or deformed. Cross-section circular, thus symmetry being generally radial. Aperture diagonal, as wide as the tubes, without operculum. Mostly vagrant benthic, nektobenthic or plantonic-pelagic, sometimes sessile, attached to the substrate or some foreign shells.<\/li>\n<\/ul>\n<p>[\/accordion] [\/accordions]<\/p>\n<div>\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\">Cornulitidae<\/p>\n<p><a href=\" https:\/\/www.ordovicianatlas.org\/atlas\/mollusca\/tentaculita-2\/cornulitidae\/\"> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.ordovicianatlas.org\/wp-content\/uploads\/2014\/01\/Cornulites_corrugatus_250pxB.png?resize=250%2C250&#038;ssl=1\" alt=\"\" width=\"250\" height=\"250\" \/><br \/>\n<\/a><\/p>\n<\/div>\n<div>\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\">Tentaculitidae<\/p>\n<p><a href=\" https:\/\/www.ordovicianatlas.org\/atlas\/mollusca\/tentaculita-2\/tentaculitidae\/\"> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.ordovicianatlas.org\/wp-content\/uploads\/2013\/11\/Tentaculites_richmondensis_250pxB.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<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Classification Phylum: Mollusca Class: Tentaculita (Boucek, 1964) Cincinnatian Families: Cornulitidae, Tentaculitidae Geologic RangeResponsive Pro Options Cambrian &#8211; Carboniferous Common Paleoecology Tentaculita is an extinct class of stationary semi-infaunal suspension feeders Characteristics of the Class Currently defined as a Mollusk, however &hellip;<\/p>\n<p class=\"read-more\"> <a class=\"more-link\" href=\"https:\/\/www.ordovicianatlas.org\/atlas\/mollusca\/tentaculita-2\/\"> <span class=\"screen-reader-text\">Tentaculita<\/span> Read More &raquo;<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"parent":2695,"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-5668","page","type-page","status-publish","hentry"],"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/P3T22h-1tq","_links":{"self":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/5668","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=5668"}],"version-history":[{"count":10,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/5668\/revisions"}],"predecessor-version":[{"id":13120,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/5668\/revisions\/13120"}],"up":[{"embeddable":true,"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/pages\/2695"}],"wp:attachment":[{"href":"https:\/\/www.ordovicianatlas.org\/wp-json\/wp\/v2\/media?parent=5668"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
