Here we re-interpret <i>Odontogriphus</i> based on 189 new specimens including numerous exceptionally well preserved individuals from the Burgess Shale collections of the Royal Ontario Museum. This additional material provides compelling evidence that the feeding apparatus in <i>Odontogriphus</i> is a radula of molluscan architecture comprising two primary bipartite tooth rows attached to a radular membrane and showing replacement by posterior addition. Further characters supporting molluscan affinity include a broad foot bordered by numerous ctenidia located in a mantle groove and a stiffened cuticular dorsum. <i>Odontogriphus</i> has a radula similar to <i>Wiwaxia corrugata</i> but lacks a scleritome. We interpret these animals to be members of an early stem-group mollusc lineage that probably originated in the Neoproterozoic Ediacaran Period, providing support for the retention of a biomat-based grazing community from the late Precambrian Period until at least the Middle Cambrian.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A soft-bodied mollusc with radula from the Middle Cambrian Burgess Shale","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:58:19.190595","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2006,"MonPub":null,"DateUpdate":"2006-07-25","DateCreate":"2006-07-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000238979700038","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":101018,"PubliDate":2006,"Pagination":"159-163","XtraPublOfAnaID":null,"ISBN":null,"Volume":"442","Issue":"7099","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43431,"SerRR":"Nature: International Weekly Journal of Science.
