Tertiary and Cretaceous Brachiopods from Cuba and the Caribbean

Abstract

Thirty-nine taxa of fossil brachiopods are described, figured, and discussed. Three come from Cretaceous rocks of Cuba and the remainder were found in Tertiary sediments of Cuba and other parts of the Caribbean region. These range in age from Eocene to Pliocene. Fourteen genera are identified of which two are new: one from the Cretaceous and the other from the Eocene, both from Cuba. Thirty species are recognized among the fossil genera: Cruralina, 1 (new); Terebratulina, 1 (new); Tichosina, 2 new; Tichosina?, 3 (1 new); Stenosarina, 1 (new); Gryphus, 4 (2 new); Gryphus?, 1; Dyscritothyris, 1 (new genus and species); Argyrotheca, 12 (11 new); Cistellarcula, 1 (new); Hercothyris, 2 (new genus and 2 new species); Lacazella, 1. Representatives of the following genera are not identified specifically: Cryptopora, Rugia, Terebratulina, Platidia, Argyrotheca, Thecidellina.
