Il est montré que les deux groupes sont déjà clairement individualisés au début du Messinien et qu ’ils survivent en Méditerranée au Pliocène, puis au Quaternaire sans grandes modifications morphologiques. Les deux groupes ont donc survécu à l ’événement dit “crise de salinité”  du Messinien. À ce titre, la présence du groupe <i>B.</i>gr. <i>lyrifera</i> est démontrée dans les marnes et calcaires interstratifiés au sommet des gypses du site de Los Yesos, dans le bassin de Sorbas (SE Espagne). Alors que les <i>B.</i> gr. <i>lyrifera</i> comptent actuellement parmi les spatangues typiques des milieux les plus profonds (circalittoral à bathyal), ils étaient déjà associés, dans le Messinien pré-évaporitique, aux faciès à échinides les plus distaux, dans des bathymétries supérieures à celles où vivaient les <i>Clypeaster</i> et les <i>Schizaster</i>. Tant l’absence de ces deux derniers genres d ’oursins dans les marno-calcaires intragypses que l ’abondance des <i>B.</i> gr. <i>lyrifera</i> dans les mêmes niveaux plaident en faveur du dépôt d ’une partie des gypses sous une tranche d ’eau relativement importante. La persistance à Sorbas de tels organismes, sténohalins et marins, vers la fin de l ’épisode évaporitique, indique des connexions entre le bassin de Sorbas et des zones marines franches pendant cet épisode.","AbstractOtherLang":"The synthetic analysis of Messinian, Plio-Pleistocene and Recent spatangoids of the genus <I>Brissopsis</I> has allowed to describe the morphological variations of Mediterranean representatives of these echinoids,following the variations of the two morphological groups <I>B.</I> gr. <I>atlantica</I> and <I>B.</I> gr. <I>lyrifera</I> from the Late Neogene to the Present-Day. It is shown that the two groups were clearly differenciated during the Messinian and that they survived in the Mediterranean during the Pliocene, and then during the Quaternary, without main morphological changes. So, the two groups have survived to the “Messinian salinity event ”. Moreover, the presence of <I>B.</I> gr. <I>lyrifera</I> in marls and limestones interbedded in the gypsum of Los Yesos section (Sorbas basin, SE Spain) is demonstrated. Both in Recent seas and in the antegypsum Messinian series, <I>B.</I> gr. <I>lyrifera</I> is one of the deepest spatangoids, living in deeper environments than those settled by <I>Clypeaster</I> and <I>Schizaster</I>. So, the absence of these two last echinoids and the abundance of <I>B.</I> gr. <I>lyrifera</I> in the marls and the limestones interbedded in the gypsum are arguments in favour of the gypsum deposit under relatively large depth. The survival of these echinoids, typically stenohaline and marine organisms, in the last levels of Messinian gypsum of Sorbas basin testifies the existence of marine connexions between this basin and normal marine areas during the evaporitic episode.","BibLvlCode":"AS","StandardTitle":"Évolution de la diversité des Brissopsis (Echinoida,Spatangoida)en Méditerranée depuis la «crise messinienne »: application paléoécologique aux <i>B. lyrifera</i> intragypses de Sorbas (SE Espagne)","OrigTitleLangCode":"fr","OrigTitleLangCodeExtended":"fre","OrigTitleLangID":22,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2003-08-28","DateCreate":"2003-08-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":38773,"PubliDate":2000,"Pagination":"509-523","XtraPublOfAnaID":null,"ISBN":null,"Volume":"22","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42902,"SerRR":"Geodiversitas.
