Popis: Cenomanian–Turonian ostracodes are reported from the western Colorado Plateau (Western Interior Basin) in the United States. Fifteen genera and twenty species are illustrated, six of which are new: Cytheromorpha perornata nov. sp., Looneyella leckiei nov. sp., Asciocythere posterangulata nov. sp., Asciocythere arizonensis nov. sp., Cytheropteron clavifragilis nov. sp. and Hourcqia dakotaensis nov. sp. Three ostracode interval zones are proposed that broadly correspond to the existing late Cenomanian through to Middle Turonian Ammonite-zones of Kauffman et al. (1993). Paleoenvironments range from estuarine to coastal plain.
