Systematic study of the historical material of Upper Cretaceous reptiles from the Tremp Basin (Catalonia, Spain) housed at the Museo Nacional de Ciencias Naturales (Madrid)

Abstract

Purpose The development of the studies on Mesozoic reptiles of the Spanish record occurred much later than in several European countries such as United Kingdom, France or Germany. Thus, very scarce and punctual findings were performed in the second half of the 19th century, followed by the work of Jose Royo y Gomez, which was stopped by the Spanish Civil War. The professional surveys and studies carried out in the 1950s in the Upper Cretaceous levels of the Tremp Basin (Lleida, Catalonia, Spain) can be considered as the origins of the development of this discipline in Spain. The works in the Tremp Basin were performed through the collaboration of national and foreign researchers. The Spanish palaeontologist Emiliano Aguirre and the French Albert Felix de Lapparent published some preliminary notes on the vertebrate fauna identified there. However, no detailed systematic study of these historical remains was ever done.
