Lithology description: "Occurs in greenish-gray and gray marls with interbeds of argillaceous limestones belonging to the fourth facies zones...Sedimentation...took place in a pericratonic basin under conditions of increased terrigenous material supply. [Conflicting evidence on depth discussed in detail: BA assignment difficult: perhaps 2,3, or 4]. More than 95% of D. n. specimens articulated..[indicating] quiet water...below or at wave base under dysaerobic conditions (suggested by gray...marl)."
