Resumen

Chelonian plate remains from the uppermost Cretaceous (Maastrichtian) of the Lleida Province in Catalonia are described for the first time. Both cryptodire and pleurodire turtles are represented in the assemblage. An hypoplastron from Fontllonga (Ager syndine) and a peripheral plate fragment from Biscarri, near Isona (Tremp Basin) are referred to a bothremydid cf. Polysternon sp.; isolated pleural and peripheral plates from an indeterminate locality of the Tremp area are assigned to the Solemydidae as cf. Solemys sp. Both Polysternon and Solemys are fresh-water turtles and common components of the continental vertebrate fauna of the Ibero-Occitan realm at the end of the Cretaceous
