Article: Some larger foraminifera from the Tertiary of Central America
Some larger foraminifera are recorded from various localities in the Central American region, many of them being illustrated. Additional information concerning, and new illustrations of, topotype material of some previously known forms are given. New subgenera Vlerkina and Vlerkinella (of the genus Heterostegind) are proposed; four new species and one new subspecies are described and illustrated. Certain aspects of the stratigraphy of the region are discussed, and the genus Pliolepidina is acknowledged to range down to the Late Eocene. The Oligocene age of certain occurrences of large foraminifera is confirmed by the associated planktonic foraminifera.
