2.) Reference and study materials:
2.1) Reference collections to Bartenstein, H., Bettenstaedt, F., and Bolli, H.M. (1957 and 1966), and Bartenstein and Bolli (1973, 1977, and 1986).

The materials ncludes washed residues and Trays 1 through 4 with assemblage slides and picked foraminifers on Toco Formation and Cuche Formation of Trinidad. Link to H.G.Kugler's Strarigraphic collection of Trinidad (Toco Formation), (Cuche Formation) and (Maridale Member of Cuche Formation). Received from Bartenstein on 6 October 1986. For primary types see collections under 1.) further above.
