The conodont fauna described and illustrated in this paper has been collected from a single fossiliferous horizon within the Ottre Formation, at the transition between the Meuville Member and the Les Plattes Member. This is the first record of a conodont fauna from the Stavelot Inlier in Belgium. It is also of interest for regional stratigraphy, international correlation, as well as for palaeobiogeographic interpretations, because the Salm Group forms an epimetamorphic, comprehensive series of nearly a thousand meters in thickness but is poorly dated.The biostratigraphical comparisons suggest an Early Ordovician, tentatively latest Tremadocian age for the conodont assemblage, but a basal Arenig age cannot be excluded. The fauna is clearly dominated by typical drepanodiform elements, but there is quite some morphological variation in this small simple cone assemblage from subrectiform (of <i>Drepanoistodus?</i>) to reclined and recurved elements. The most common elements belong to <i>Drepanodus arcuatus</i> PANDER 1856 ranging from the uppermost Tremadocian up into the lower Darriwilian (= uppermost Arenig). However, there are also a few elements in the fauna from the Salm Group, like some strongly recurved <i>\"Drepanodus\" recurvatus</i> SANNEMANN 1955, which are comparable to the latest Tremadocian <i>'franconicus'</i> fauna, characteristic for the Frankenwald area. The species diversity is very low which is comparable to the situation in cold water areas of the Mediterranean Province of Gondwana and peri-Gondwana like the Frankenwald region, the Barrandian area and the Montague Noire.The discovery of this small conodont fauna enhances our knowledge not only of the chronostratigraphy of the Salm Group, but also of the palaeogeographical situation of the Belgian Ardenne in Early Ordovician times.","AbstractOtherLang":"Une faune à conodontes a été découverte dans deux localités de la vallée de la Lienne à proximité de Chevron dans les dépôts faiblement métamorphiques du Groupe de la Salm du Massif de Stavelot. La faune, décrite et illustrée dans cet article, provient d'un même horizon au sein de la Formation d'Ottré. Cet horizon est situé juste à la limite entre les Membres de Meuville et de Les Plattes. C'est la première fois qu'une faune à conodontes est trouvée dans le Massif de Stavelot. Son intérêt pour la stratigraphie régionale, pour les corrélations internationales, de même que pour des interprétations paléobiogéographiques est manifeste étant donné que le Groupe de la Salm constitue une série compréhensive épimétamorphique, épaisse de près de 1.000 mètres et mal datée.Les premières comparaisons biostratigraphiques suggèrent pour l'assemblage un âge Ordovicien Inférieur, peut-être Trémadocien supérieur, quoiqu'un âge Arénig inférieur ne puisse pas être exclu. La faune est typiquement dominée par des éléments drepanodiformes, mais il y a une variation morphologique importante dans ce petit assemblage de cônes simples entre des éléments subrectiformes (<i>Drepanoistodus?</i>) à des éléments inclinés et incurvés. Les éléments observés les plus communs appartiennent à l'espèce <i>Drepanodus arcuatus</i> PANDER 1856. Cette espèce s'étend stratigraphiquement du Trémadocien supérieur au Darriwilien inférieur (= Arénig supérieur). Il y a aussi dans la faune étudiée quelques éléments de la faune <i>'franconiens'</i>, caractéristique de la région de Frankenwald, datée du Trémadocien supérieur. La diversité spécifique très faible est comparable à la situation qui existe dans des régions d'eau froide de la Province Méditerranéenne (Gondwana et péri-Gondwana) telles la région de Frankenwald, la région Barrandienne et la Montagne Noire.La découverte de cette petite faune à conodontes enrichit nos connaissances non seulement de la chronostratigraphic du Groupe de la Salm, mais aussi de la position paléogéographique de l'Ardenne belge à l'Ordovicien Inférieur.","BibLvlCode":"AS","StandardTitle":"Discovery of an Early Ordovician conodont fauna in the Salm Group of the Stavelot Inlier, Belgium","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Conodont biostratigraphy, palaeogeography, peri-Gondwana","OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2014-02-20","DateCreate":"2014-02-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":233766,"PubliDate":2004,"Pagination":"39-48","XtraPublOfAnaID":null,"ISBN":null,"Volume":"74-suppl.","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":64308,"SerRR":"Bulletin van het Koninklijk Belgisch Instituut voor Natuurwetenschappen.
