International audience. A sub-complete axial skeleton of Enaliosuchus macrospondylus Koken, 1883 (Crocodylia, Metriorhynchidae) has been discovered in the Lower Valanginian (Campylotoxus Zone), near Barret-le-Bas (Hautes-Alpes, Southeastern France). This specimen is the most complete and the best stratigraphically constrained of this genus. Only, two others less complete specimens are known. This specimen is one of the last metriorhynchids known. It shows a unique case of high nares raising for a crocodilian, a characteristic still unknown among this taxa. . Un squelette axial sub-complet d'Enaliosuchus macrospondylus Koken, 1883 (Crocodylia, Metriorhynchidae) a été découvert dans le Valanginien inférieur (zone à Campylotoxus) de la région de Barret-le-Bas (Hautes Alpes). Ce squelette est le plus complet et le mieux calé stratigraphiquement appartenant à ce genre. Seuls deux autres spécimens plus fragmentaires sont connus. Cet animal représente l'un des tout derniers Metriorhynchidae connus. Il présente un cas unique de remontée des narines externes chez un crocodilien, caractère inconnu jusque là dans ce taxon.
