Dans les environnements favorables du Dévonien de l’Ardenne occidentale, les trilobites sont des composants majeurs du macrobenthos. Une analyse des changements de la paléobiodiversité et une modélisation de la répartition des communautés à trilobites du massif des Ardennes au Dévonien sont proposées. Le pic de diversité est atteint à l’Eifélien (Dévonien moyen) quand le système carbonaté est développé. Six associations ont été reconnues à l’aide des analyses de classification hiérarchique. La distribution de ces associations est corrélée aux conditions écologiques et temporelles.

Key Words: Trilobites • Dévonien • Ardenne occidentale • Biodiversité • Assemblages
