[FR] Dans cet article nous décrivons les restes fossiles du genre Indarctos Pilgrim, 1913 du Miocène supérieur (MN13) de la localité de Las Casiones (Teruel, Espagne). Bien que les relations phylogénétiques de ce genre soient encore controversées, dans l’analyse phylogénétique la plus récente basée sur les caractères crâniens, mandibulaires et dentaires, ils sont inclus dans les Ailuro podinae. Ces parents des pandas géants étaient donc les ours prédominants dans les assemblages de carnivores pendant la majeure partie du Miocène supérieur de la péninsule Ibérique. D’autre part, ces fossiles d’Indarctos punjabiensis (Lydekker, 1884) représentent la dernière population de cette sousfamille dans les archives fossiles de la péninsule Ibérique, et éventuellement aussi d’Europe, ils contribuent de manière significative à l’avancement de la connaissance de l’histoire évolutive de cet groupe. En outre, nous signalons le remplacement de Indarctos par Agriotherium Wagner, 1837 dans les faunes ibériques entre 6.3 et 6.23 Ma.

[EN] In this paper we describe Late Miocene (MN13) remains of the genus Indarctos Pilgrim, 1913 from the locality of Las Casiones (Teruel, Spain). Although the phylogenetic relationships of this genus are still controversial, the most recent phylogenetic analyses, based on cranial, mandibular and dental characters, include it in Ailuropodinae, thus making the relatives of the giant panda the predominant bears in the carnivoran assemblages for most of the Late Miocene in the Iberian Peninsula. These fossils of Indarctos punjabiensis (Lydekker, 1884) represent the last population of this subfamily from the Iberian fossil record, and possibly also from Europe, making this an important advance in our knowledge of the evolutionary history of this group. We also note the replacement of Indarctos by Agriotherium A. Wagner, 1837 in Iberian faunas, between c. 6.3 and c. 6.23 Ma.
