It is generally assumed that they are pelagic, more precisely planktonic or nektoplanktonic, and that their presence is indicative of deep environments. However, a purely morphological study is not sufficient to determine their mode of life. Their relationship with the substrata and other animals, and their response to major environmental changes must be taken into account. These data confirm a swimming mode of life for all the entomozoaceans, and suggest that a nektobenthic lifestyle, in poorly oxygenated, but not necessarily deep, environments is more probable than a planktonic mode of life. The presence of a Myodocopid Mega-Assemblage proxy for hypoxic events, seems more useful that the differentiation of an \"Entomozoid ecotype\".","AbstractOtherLang":"Les Entomozoacea constituent une super-famille d'ostracodes appartenant à l'ordre des Myodocopida. Ils ont en commun une taille relativement grande, des valves égales peu calcifiées, et une ornementation souvent comparée à des empreintes digitales. Elle leur confère une grande valeur biostratigraphique. La plupart des ostracodologistes estiment qu'ils étaient pélagiques et plus précisément planctoniques ou necto-planctoniques, et que leur abondance dans les sédiments témoigne par conséquent d'une grande profondeur de dépôt. Mais l'étude morphologique seule ne suffit pas pour déterminer leur mode de vie. Leur relation avec le substrat et avec les autres organismes, ainsi que leur comportement lors des changements environnementaux majeurs doivent aussi être pris en considération. Ils montrent que les Entomozoacea étaient plutôt necto-benthiques et opportunistes dans des milieux pauvres en oxygène dissous, mais pas nécessairement profonds. Un Mega-Assemblage à Myodocopida caractérisé par la présence d'Entomozoacea et (ou) de Cypridinacea (= Assemblage V de CASIER <i>et al.</i>, 1985; CASIER, 2003) peut servir d'indicateur pour les événements hypoxiques dans le Dévonien.","BibLvlCode":"AS","StandardTitle":"The mode of life of Devonian entomozoacean ostracods and the Myodocopid Mega-Assemblage proxy for hypoxic events","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":"Ostracods, Entomozoacea, Devonian, Mode of life, Palaeoecology","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":233772,"PubliDate":2004,"Pagination":"73-80","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.
