Hypolites sp. rare Murichsonia sp. rare -> (Belkeroglypt (5) of Cyra ?? [illegible] ?) (Yelonema sp.) occasional Pteroceras spinatum (few with markings) R Orthoceras 3 species (1) annulated & longitudinal striate; occasional (2) " " reticulate " rare (3) small Monotrypa (small) occasional large " abundant in one seam Hindia fibrosa occasional Crinoid Jointy columns occasional Serpulites sp. rare Wednesday July 31, 1907 (A.18) collected from 5:3:8 F. 264 then the shales containing the rich fauna 5:3:8 F as immediately underlaid by 3 feet of shales which are similar lithologically except that they are more bonded & i as taken by a three foot underlying trap shale. These looked slates 5:3:8 G, also contain a couple of large seams and in one of these fossils were collected consisting of Dalmanella (coarse) abund Rhynchonella sp. rare Chonetes denzeri sp. " Syringopora? Clamipes) " Strike N. 45° W. x S.E., dip 35° N.E. Three shales as followed down and in the section following the section down and the three feet of laked slates 5:3:8 & about against a three foot trap dips which seems very nearly along the line of strike. This strike to 1/32 and bears N. 45° W. Below the strike 1/32 is a covered material about 10 feet broad and then more thick crops out a calcar- eve all in a foot thick containing fossils, chiefly Hindia fibrosa abundant Dalmanella coar. Rtzia Pteronotella n Actinopteria rare Cornulites serpularius rare This volcanic ash strikes N. 42° W and dips 35° to the N. 40°. The fossils are 5:3:8 H. Thursday, Aug. 1, 1907. Following the section continued as a covered trap below 5:3:8 H shales is "a covered top about 8 feet wide on the slope and then crosses a rocky point consisting of some thick slates of the base and top and a thick massive triff lacing in the middle. The upper shales are or four feet thick colors observed and break into large splintery chunks, bedding planes not well developed. These slates contain occasional spots with little ash fragments indicating that the period of volcanic activity represented by the underlying trap became extended sporadically. These overlying shales also contain large boulders mostly the same of the shales is 5:3:8 K and includes Dalmanella (coarse) abund Archeodesma (small). rare Chonetes denzeri rare Rhynchonella (? Rhynchotrema) common Crinoids. occasional Cornulites serpularius rare; Mediolopsis & platyphyllus occasional Actinopteria n. Grammysa conglobata (Cagtypical). rare Cyclostoma sp. rare Orthoceras loderense common: The Orthoceras is something as much as 2 inches or a little more
