48 cont The overlying 17 feet 4 inches are undoubtedy of Clintonage. The limestone is here well bedded, and often quite calc- careous to as to have a whit-ish color, especially along the upper surface of many of the layers. In parts of the section these Clinton beds are so re-naceous and so thinly bedded, as to resemble very much the banded Madison rocks. At various levels the Clinton limestone cuts away lenses and nodules of chert, es-pecially along the upper surface of the various layers, and on the upper surface of this chert all the fossils are found. The upper 2 feet 8 inches of the limestone is again un-fossiliferous. It is more-a-re-naceous, has a light brown color, and breaks in-to irregular small blocks. It seems to form a sort of transition to the lower Co-good shale and corresponds probably to the basal Nia-gara of the Indiana section. 9 48 cont The fossils of the undoubted Clinton are best exposed on all of the bridge or the right side of the stream as far north as the Clinton exposed. Most of the fossils occur in the upper third of the Clinton. Orthus flabella and Orthus bifurcata occur very sparingly in the lower two thirds. Orthus flabella is considered characteristic of the Clinton. The following is a list of the Clinton fossils seen: Dalm anites Wortlineri, pyg. Illacenus ancligenus 6 pyg. " " " Daytonensis 1 pyg. (in calcareous Clinton) Orthus flabella Orthus bifurcata Orthus elegatula Streptoclema, flat, raised beak as in Dayton Clinton. Plectamunites sericea with distant raised plication. Plectamunites sericea, very curves and warin as in southern Clinton. Rhizodontia medium, small. Farnity Niagarensis, medium large, large Crabrum.
