The phylum Bryozoa, the colonial ‘moss animals’, have been the exception: convincing skeletons of this biomineralizing clade have been absent from Cambrian strata, in part because potential bryozoan fossils are difficult to distinguish from the modular skeletons of other animal and algal groups. At present, the strongest candidate is the phosphatic microfossil <i>Protomelission</i>. Here we describe exceptionally preserved non-mineralized anatomy in <i>Protomelission</i>-like macrofossils from the Xiaoshiba Lagerstätte. Taken alongside the detailed skeletal construction and the potential taphonomic origin of ‘zooid apertures’, we consider that <i>Protomelission</i> is better interpreted as the earliest dasycladalean green alga—emphasizing the ecological role of benthic photosynthesizers in early Cambrian communities. Under this interpretation, <i<Protomelission</i> cannot inform the origins of the bryozoan body plan; despite a growing number of promising candidates there remain no unequivocal bryozoans of Cambrian age.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"<i>Protomelission</i> is an early dasyclad alga and not a Cambrian bryozoan","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-13 01:33:46.033164","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2023,"MonPub":null,"DateUpdate":"2023-04-04","DateCreate":"2023-04-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000946936400013","VABBcode":null,"OpenAcc":0,"DOI":"10.1038/s41586-023-05775-5"},"refs":null,"anarec":{"AnaID":363222,"PubliDate":2023,"Pagination":"468-471","XtraPublOfAnaID":null,"ISBN":null,"Volume":"615","Issue":"7952","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43431,"SerRR":"Nature: International Weekly Journal of Science.
