The studies focus mainly on the echinoidea of the platforms and basins of the upper Cretaceous. The main deposits being worked on are located in the foothills of the Catalan and Aragonese Pyrenees, such as the Basturs hills, the Balluguera gorge and the Paúl gorge in Villacarli, and in the Betic and Crevillente mountains, for example, in the Elche reservoir (Alicante) and Cieza (Murcia), where the echinoidea of the deep-water facies of the upper Cretaceous and the palaeobiogeographic provinces. Studies are also being done of the different deposits of the Central System, where the echinoidea of the upper Cretaceous are being studied (with Dr. M. Segura, UAH, Alcalá de Henares). There is a project in Costa Rica (Caribbean), which is studying echinoidea of the upper Cretaceous with Dr. B. E. Buitrón (UNAM, Mexico D. F.), Dr. J. M. Pons (UAB, Bellaterra) and Dr. Schmidt-Effing (Univ. of Marburg, Germany). In recent years, fieldwork has begun on the Cretaceous Period in the region of Dobruja (Romania) both from the south (Constanza region) and the north (Babadag basin, near Tulcea), in collaboration with Dr. Iuliana Lazar of the University of Bucharest.
