Localities along Fox Hills ridge extending eastward from Wasserburger Ranch. In secs 17, 18, 19 and 20, T. 37 N., R. 62 W. In this area the axis of the North Ant Hills anticline lies approx. along the east line of the township, consequently the outcrops in SW cor sec. 18 show lower part of section (loc. 103) and those in NW sec 20 and SW 17 (loc. 104) show upper part. Fairly complete composite section from Pierre contact well into "banded beds" should be possible. Locality 103 - Collected from "Veniella" zone - in other words the entire massive unit, without discriminating convection horizons. Transition back to Pierre include a pyrosite layer or two but no fossils seen Locality 104 For convenience in collecting the massive unit was divided into parts based on the local convection layers. These are roughly as follows: - more details next page CONC LAYER A4739 #1 Top D thin-bedded sh + ss phosphatic nodule layer Veniella + assorted stuff in phosphatic layer, incl.
