Article: The foraminiferal genus Bolivinoides from the Upper Cretaceous of the British Isles

Nine species of Bolivinoides are described from the Upper Cretaceous (Santonian to Lower Maestrichtian) strata of the British Isles, and their stratigraphical ranges are recorded in relation to the classical mega-fossil zonation. Three of these species, Bolivinoides hiltermanni, B. praetaevigata, and B. sidestrandensis, are described as new and a lectotype is proposed for B. decorata (Jones). The phylogeny of various lineages of the genus Bolivinoides is discussed.
