An upper Maestrichtian assemblage of planktonic foraminifera is described from a sample of chalk dredged from Galicia Bank, a non-magnetic seamount off the west coast of Spain. The presence of post-Maestrichtian planktonic species in the sample is attributed to the burrowing of mud-feeding organisms. It is suggested that the very high percentage of planktonic individuals in the upper Maestrichtian limestone of Galicia Bank is a product of depth and proximity to an open oceanic environment during deposition.
