ResumoThe presence of continental turtles in the Ainsa Basin (south-central Pyrenees, northeast Spain) is reported here for the first time. These specimens come from the middle-late Lutetian of the Sobrarbe Fm. Four clades are identified there. One of them corresponds to a member of Pleurodira, identified as Neochelys cf. salmanticensis. The others are cryptodiran turtles, recognized as an indeterminate member of Testudinidae, and two soft-shelled turtles: the carettochelyid Allaeochelys sp. and the trionychid Trionyx sp. This association of turtles is the most diverse identified in the Lutetian of the Iberian Peninsula. The identification of a member of Testudinidae corresponds to the oldest Iberian record of this clade. This turtle fauna is more similar to that present in the Iberian Duero Basin than in any other European region.
