Occasional complete Dalmanites and Trimerus Mudstone beds with sparse shell pavement and occasional complete Dalmanites Thick Striispirifer bed with scattered pieces of bryozoan, trilobites, crinoids and other fauna. Mudstone containing Dalmanites bed #1 with brittle stars and Homocrinus crinoids on assorted shell pavement at base. Occasional complete crinoids found.
