Occurrence of Dictyocha (silicoflagellates) in the Upper Cretaceous of Wyoming and Colorado
Karl W. Klement
Two silicoflagellate species, Dictyocha speculum and D. crux are described from the Upper Cretaceous of Washakie Basin, Wyoming and Colorado, and Piceance Creek Basin, Colorado. This is, to the knowledge of the author, the first clearly established record of an occurrence of Dictyocha (previously known from Tertiary to Recent) in Cretaceous sediments.
