A restudy of the extant, motile-defined <i>Micracanthodinium setiferum</i> using plankton samples from the Indian and Atlantic oceans and the Mediterranean Sea demonstrates that the correct plate formula is Po, Pt, X, 3′ + *4′, 4a, 7′′, 7C, 4S, ?6′′′, 0p, 2′′′′. A ventral pore is found between 1′, 3′ and *4′. A restudy of the extinct, fossil-defined <i>Cladopyxidium saeptum</i> from the upper Paleocene of Delaware (USA), demonstrated the presence of an identical tabulation. A ventral pore (= porichnion) was positioned between *1′ and 7′′. <i>Cladopyxidium</i> is morphologically closer to <i>Micracanthodinium</i> than to <i>Cladopyxis</i>. Since <i>Cladopyxidium</i> has been extinct since the middle Eocene, it is unlikely that <i>Micracanthodinium</i> and <i>Cladopyxidium</i> have a direct biological link; the close morphological similarity between them does, however, suggest an important phylogenetic relationship between them in the evolution of cladopyxidaceans.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A morphological comparison of two cladopyxidacean dinoflagellates: the extant <i>Micracanthodinium setiferum</i> and the fossil <i>Cladopyxidium saeptum</i> (Dinophyceae, Gonyaulacales)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"dinoflagellates; partiform; Kofoidian; porichnion; Paleocene; Eocene","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2023-03-28","DateCreate":"2023-03-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000674068200001","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/01916122.2021.1934908"},"refs":null,"anarec":{"AnaID":362725,"PubliDate":2022,"Pagination":"1-17","XtraPublOfAnaID":null,"ISBN":null,"Volume":"46","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":181551,"SerRR":"Palynology.
