"The most abundant and diverse family in the assemblage is the Lagenidae, but arenaceous Foraminifera are also numerous. At almost every horizon two species, Ammobaculites coprolithiformis (Schwager) and Lenticulina muensteri (Roemer), comprise more than half the specimens found. The assemblage described is typically Oxfordian in composition, and its affinities are with the preceding Jurassic faunas rather than with those of the lower Cretaceous. . . . Four species are described as new."
