Latitudinal variation in the planktic foraminifer Contusotruncana contusa in the terminal Cretaceous ocean ...

The morphological variability (coiling properties, size and shape) of the planktic foraminifer Contusortuncana contusa (Cushman) in the terminal Cretaceous ocean was examined at eight deep-sea sites and two continental sections from low (16°) to middle (42°) paleolatitudes in both hemispheres. The m...
