She argued that these genera have a similar budding pattern with long zooecia having larger diameters in the axial part. The family Aisenvergiidae contained originally three genera: <em>Aisenvergia<\/em> Dunaeva, 1964, <em>Volnovachia<\/em> Dunaeva, 1964 and <em>Polycylindricus<\/em> Boardman, 1960. However, these genera are characterised by completely different wall structure (predominantly merged, without visible zooecial boundaries), and presence of exilazooecia instead of mesozooecia. Therefore, Astrova (1978) criticized the placement of <em>Eridotrypa<\/em>, <em>Lamottopora<\/em> and <em>Newportopora<\/em> in the family Aisenvergiidae.<\/li>\n<\/ul>\n<p><em> Ross (1967) <\/em>:<\/p>\n<ul>\n<li>Characterized by dendritic colonies with tubular zooecia whose diameter is reduced in the subperipheral region where zooecial tubes bend and zooecial walls thicken. The earliest representative of the Aisenvergiidae is the Chazyan genus <em>Lamotopora <\/em> Ross (1963). In addition to the reduced diameter of the zooecial tubes in the subperipheral region, this genus has in the axial region crenulate zooecial walls and zoocial tubes that lack diaphragms; in the well defined peripheral region the zooecial tubes generally lack diaphragms, the mesozooecia have numerous thick diaphragms, and the broad amalgamate zooecial walls have long lamina which are penetrated by distinct acanthopores.<\/li>\n<li>Dendritic colonies have tubular zooecia which are polygonal in cross section in the axial region. Zooecia form an elbow-shaped bend near the periphery and are greatly reduced in diameter in the subperipheral region;<br \/>\noccasionally the zooecial tubes are completely constricted so that in transverse section, a circular line marking the region of constriction divided the axial and peripheral regions. Acanthopores and mesozoocia are generally present in varying numbers but they are absent (After Dunaeva, 1964).<\/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>Eridotrypa<\/em><\/p>\n<p><a href=\"https:\/\/www.ordovicianatlas.org\/atlas\/bryozoa\/stenolaemata\/trepostomatida\/aisenvergiidae\/eridotrypa\/\"> <img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.ordovicianatlas.org\/wp-content\/uploads\/2015\/04\/eridotrypa-briarus-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: Trepostomatida Family: Aisenvergiidae (Dunaeva, 1964) Cincinnatian Genera: Eridotrypa Geologic Range Lower Ordovician-Carboniferous Common Paleoecology Aisenvergiidae was an extinct family of stationary epifaunal suspension feeders.
