Cretaceous to Quaternary planktonic foraminifera in ODP Leg 149 holes

This paper presents the results of a biostratigraphic analysis, based on planktonic foraminifers, of Ocean Drilling Program Leg 149 Sites 897- 900 in the Iberia Abyssal Plain, off the coast of Portugal. Dissolution and changes in water-mass temperatures affect the quality of biozonation in some leve...
