Article: Freshwater ostracods from the Bathonian of Oxfordshire
R. H. Bate
Eight species of freshwater ostracod are described from the Bathonian of Oxfordshire as exposed in the Old Cement Quarry, Kirtlington, near Oxford. Because of the number of specimens available only two, Timiriasevia mackerrowi sp. nov. and Theriosynoecum kirtlingtonense sp. nov., are identified specifically. Other genera represented are:—Bisulcocypris; Darwinula; and Limnocythere. The presence of these freshwater ostracods in marine sediments and associated with marine ostracods is considered to be due to their being brought into the area by rivers. The occurrence of two species of Timiriasevia from this country is the first recorded indenti-fication of the genus outside the U.S.S.R.
