the Indian Laddus. Thickness of Marlins 30 ft. The "Transition series" to Coeymans is here 12 feet thick and the Coeymans 18 feet. The Coeymans begins sharply above the "Transition" beds and as the Rypidula galacta are at the bottom with a regular Old delubrian fauna but without the O. macropleura there is a big faunal difference with the beds = Marlins below. In all probability there is a break in the section here that must be looked into tomorrow.
