(a) Fossils in (a) = 3.33.7a and include Lingula & a few small Modiolospoids. (b) 3 ft. red shale containing of red sandy shales, "2" to "5" with a few fluggy seams "1" to "3". No fossils. Mud cracks on one or two surfaces. Also in 2 calcareous seams 1" thick. (c) 3 ½ ft. very light gray sands beds with niterious structure. The middle bed contains 3 flags, "1" to "3" thick. (d) 6 feet red shales & a few red flags similar to (b) less without calcareous seams. Wormmarks occasional. Fossils in a seam near the top include Ligeridita, Lingula & small Modiolospoids = 3.33.7.b. (e) 2 feet massive gray sand of thin shelly flag and gray shale with a couple of calcareous seams. Fossils few lingulids, several Modiolospoids & an occasional Lepidodis (not selected). (f) 9 feet of thinly bedded red and mottled red-gray rocks consisting of fine grained sandstone & shale with thin shelly partings on with thick, rarely 3 inches. Thick c.d.e. of strike W.80°N. and dip 38° to the north. (g) A massive columnar gabbro = 110 with most thick columns a foot or more across and perpendicular tables inclined lots of (f) about 50 feet thick. (h) 2 feet gray flags, and shales. (i) ½ feet red shale. (j) 9 feet of thinly flag, and gray shale with a few very fossiliferous calcareous seams. Also a few oleo grains very fossil -sferose. Fossils Modiolospoids v Lingula and what appears to be a free Spirorthe or Autostepus, but apparently no Lingulida. Fossils (f) = 3.33.7c (k) Nine feet of massive rocks, consisting of gray flags and shales with some calcareous seams full of Modiolopsis. (l) the beds both are cut by a trap dike 1111 (M) A series of 110 feet of gray flags and shales. The flag points thick to 5" in places there are thin flags, and in the middle occur a couple of massive "8" to "10" quartzose flags. The shales are in thin partings not more than a couple of inches thick. Calcareous seams, and shell hash lenses common in places. Fossils in seams Modiolopsis, Lingula & Lepidodis (not selected). Strike S.70°W to 80°W. Dip N.36°. (M) is cut by a trap dike; relations to gabbro unknown. (N) Gabbro = 112 (O) About 140 feet of gray shales and thin flags similar to (M), and cut by 2 ten foot trap dikes one of which is ½/3, (possibly more fine grained). Contains fossils - brow seams with great numbers of small Modiolospoids, in the shale and thin flag layers. These fossils = 3.33.7.d / reads in 3.32-6; south edge of Lepidodis v Lingula also occur in same seams. Strike S.77°W Dip 36-38° more or less. (P) 20 feet of red shales with a couple of feet of gray shale in the middle. Worms marked & mud cracked. Strike S.22°W. Dip 30°, N.20 W. Fossils abundant in seams, Lepidodis, Modiolopsis v Lingula = 3.33.7.e. (Q) 10 feet gray sandy shales and flags. Same strike. Dip 35°N.20W. Freshly were marked - a few mud cracks also. Lepidodis abundant in a couple of seams with an occasional Briddlbranch and a very rare Lingula = 3.33.7.f. (R) Mostly covered. Occasional out-crops gray shale v gray flags, ostraca commoner near the top where a few calcareous seams occur. Fossils. Latitude Katabi - but not in the ward.
