Micropaleontology of a part of the Lower Cretaceous in Kent Quandrangle, Texas

Micropaleontologic and lithologic data obtained from several exposures of Finlay, Duck Creek and Fort Worth equivalents are recorded for comparison with similar information from other areas. Biostratigraphic and paleoecologlcal inferences have been made. Evidence obtained from ostracodes and foraminifera indicates that a Finlay equivalent, not Kiamichi, is present north of Kent. There is a lack of information on the Fredericksburg-Washita contact as it is not exposed within the area studied. For the most part the Duck Creek and Fort Worth equivalents were deposited in a sea of normal marine environment with depths of 5 to 60 fathoms, the only exception being in the upper portion of the Duck Creek equivalent whZere evidence indicates a slight restriction and possible regression of the sea.
