RÉSUMÉ
Le gisement paléontologique de Montoussé (Montoussé, Hautes-Pyrénées, France), découvert par Édouard Harlé en 1892, est daté du Pléistocène inférieur (1,2-1,5 Ma) pour la brèche 5. Elle renferme un grand nombre d’espèces de petite à moyenne taille, dont une série homogène et importante en terme de restes de petits mustélidés. Cet article se concentre sur leur analyse morphologique et ostéométrique à travers un corpus de 52 restes. Nous proposons ici une analyse morphologique et métrique, afin de produire des clefs d’identification discriminant la belette Mustela nivalis Linnaeus, 1766 de l’hermine Mustela erminea Linnaeus, 1758, ainsi que leurs formes fossiles respectives Mustela praenivalis Kormos, 1934 et Mustela palerminea Pétenyi, 1864. Cette identification spécifique est discutée à la lumière du contexte chrono-climatique. En effet, ces petits carnivores sont particulièrement sensibles aux variations climatiques et une corrélation est établie entre leur taille et l’environnement. Une meilleure connaissance de la variabilité inter et intraspécifique de ces espèces pourrait conduire à en faire des marqueurs paléoenvironnementaux valables. L’étude de la variabilité chez les formes anciennes remet en question leur valeur spécifique.
