A temporary construction site in the city of Antwerp (NW Belgium) gave the opportunity to study the poorly known early Miocene Kiel Sand Member of the Berchem Formation. In this Burdigalian deposit, a previously unknown fossiliferous horizon with <i>Glycymeris</i> and <i>Cyrtodaria</i> was sampled which contained a single <i>Megachasma</i> tooth. This specimen, attributed to <i>Megachasma</i> aff. <i>pelagios</i> by its resemblance with extant <i>M. pelagios</i>, is the first in situ record from un-reworked strata in Belgium. Only around a dozen fossil Megachasma teeth have been reported from Europe. It is concluded that a circumglobal megamouth population existed during the Burdigalian. Some evolutionary remarks are made.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A megamouth shark (Lamniformes: Megachasmidae) in the Burdigalian of Belgium","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-25 01:33:15.958626","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Berchem Formation, Kiel Sand Member, North Sea Basin","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2021-05-17","DateCreate":"2021-03-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000607869400010","VABBcode":null,"OpenAcc":1,"DOI":"10.20341/gb.2020.001"},"refs":null,"anarec":{"AnaID":334866,"PubliDate":2020,"Pagination":"157-165","XtraPublOfAnaID":null,"ISBN":null,"Volume":"23","Issue":"3-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45707,"SerRR":"Geologica Belgica.
