In total, twelve taxa are recognised from levels which are correlative with the Calcaire à <i>Baculites</i> of Manche (France), as well as with the Tercis les Bains section in southwest France, the Wisla (Vistula) River sections (central Poland) and the Western Interior of the United States. Associated cephalopods allow a detailed correlation between biozones based on those groups and on inoceramid bivalves.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The youngest Maastrichtian 'true' inoceramids from the Vijlen Member (Gulpen Formation) in northeast Belgium and the Aachen area (Germany)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-02 01:31:23.362875","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Bivalvia; Inoceramidae; Maastrichtian; Maastrichtian type area;correlation","OtherDescriptors":null,"Notes":null,"AnaPub":2010,"MonPub":null,"DateUpdate":"2018-08-17","DateCreate":"2013-12-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000282252400004","VABBcode":null,"OpenAcc":0,"DOI":"10.1017/S0016774600000755"},"refs":null,"anarec":{"AnaID":231459,"PubliDate":2010,"Pagination":"147-167","XtraPublOfAnaID":null,"ISBN":null,"Volume":"89","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42914,"SerRR":"Netherlands Journal of Geosciences.
