top is a zone 27 foot thick of heavy bedded li. crystalline made of marked together material, two-thirds of which is crinoid matter. Plectodoria lipnate/plates and O. testudinaria are very common, and more rare P. deltroides, P. sericus. Below this is the upper Trenton of thin bedded li. with much shale partings. In the P. deltroidea domain. It is between 75 and 100 foot thick. The ocrea or upper entated zone occurs about 30 feet below the top. P. lipnata occurs often. Dalothe quarry is in the domain and apparently about 70 feet beneath the top, but about two miles away from the stream. The lower local zone of entated strata occurs just below the upper Trenton. The lower said Trenton is more heavily bedded at midbut little shale and here fossils are much scarcer. Pias/praen, O. testudinaria, P. sericus etc. Triplecia rotana occurs near the middle of Trenton here Left Trenton Falls at 3.45- and 5.30 are gone up in the day at Martinsburg, a little inn on the upper level, out of Upper Trenton.
