Revision of the Primitiidae and Beyrichiidae with new Ostracoda from the Lower Devonian of Pennsylvania
The old families Primitiidae and Beyrichiidae are subdivided into six families: Primitiidae (emended), Beyrichiidae (emended), Hollinidae, Tetradellidae, Drepanellidae, and Acronotellidae. A seventh family, the Aechminidae, is doubtfully assigned to this group, and Primitopsidae, is proposed provisionally. The genera belonging to each family are listed. The question of the orientation of the Primitiidae and related forms is discussed.
The new genera Paraschmidtella, Milleratia, Pyxiprimitia, Parabolbina, Tubulibairdia, and Kellettina are proposed. Part of the ostracode fauna of the Lower Devonian Shriver chert of Pennsylvania is described.
