Resumen
Chelonian plates from the uppermost Maastrichtian of the Huesca Province are described. The remains have been found in the transitional and fluvial Tremp Group. The bothremydid turtle plates are well preserved and represent the most abundant elements. Only one eroded plate fragment of the solemydid turtle has been discovered. This difference is possibly due to tafonomic factors, but does not discard that the solmydids ones were more scarce because it was a group in decrease at end of Cretaceous.
