Geology comments: "...association assigned to BA 3 based on its occurrence with the Howellella Community...It is present with abundant and diverse bryozoans, brachiopods and other taxa in mudstones, which were deposited under low energy,below wavebase conditions. Trilobites disarticulated and scattered, although some...may be articulated."
