Discoveries of skeletal structures and  specimens preserved in situ, coupled with cladistic  analyses, have led to a revival of the hypothesis  that conulariids were scyphozoans. Until 1979  research on conulariids centered on the description  of new species using phenetic approaches. The 1980''s  saw the publication of papers on the paleoecology of  conulariids, and the hypothesis that conulariids  were benthic organisms was corroborated. Also, the  proposal that conulariids represent an extinct  phylum, were presented. During the 1990''s, authors  advocated either conulariids represent a separate  phylum or that they were cnidarians. Certain  advocates of a cnidarian affinity argued that  conulariids were most closely related to Canidaria.  Recently, investigators have analyzed phylogenetic  relationships among species and genera within the  group. Here is present the results of a cladistic  analysis of Conulariidae. The analysis tested  whether the three conulariid subfamilies recognized  in the Treatise on Invertebrate Paleontology are  monophyletic.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843352574\"\u003e\u003ch3\u003eSYSTEMATICS AND EVOLUTION OF A PROBLEMATICAL FOSSIL TAXON: THE FAMILY CONULARIIDAE (CNIDARIA;  EDIACARAN\/TRIASSIC)\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843352574","offer_id":39497173237853,"sku":"9783843352574","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/88dd07e5-296a-4bc4-b7e3-fbc2c4500d2a.jpg?v=1774682383","url":"https:\/\/shop.autorenwelt.de\/products\/phylogenetic-systematics-and-evolution-of-conulariids-von-juliana-de-moraes-leme-marcello-guimaraes-simoes-und-heyo-van-iten","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
