Variaciones microfaunísticas en el Cenomaniense superior a Turoniense superior de la Plataforma Norcastellana (área Puentedey-Santelices, Norte Burgos): respuesta morfológica de los inocerámidos
Analyses carried out on benthonic foraminiferal assemblages of the Puentedey-Hornillalatorre formations (Norcastilian Platform) are part of a multidisciplinary research with the main subject of understanding the palaeoceanographic events that took place at the end of the Cretaceous within the Basque...
