Book excerpt: Excerpt from Stratigraphy and Paleontology of the Credit River Section: Accompanied by Seven Plates, Also Insert Entitled "Composite Section of the Rocks of the Credit River" The source of the Credit river is on the western side of the Niagara cuesta near the village of Coningsby. From this point the river ows in a south easterly direction and empties into Lake Ontario at the village of Port Credit, seven miles west of the city of Toronto. In its upper reaches, at Credit Forks and Cataract, it cuts through the cuesta and exposes the Cataract and Lockport divisions of the Silurian, and the Queenston red shales. Between Credit Forks and Meadowvale, it winds slowly over the at-lying drift which covers the Qu'eenston shales. Two miles south of Meadowvale, the grey fossiliferous beds of the Richmond are first exposed, and from here to its mouth, a distance of about eight miles, the river cuts through these rocks in many places and in addition, exposes the upper part of the underlying formation herein called Dundas. The present study deals only with the paleontology of that part of the section below the Queenston red shales and is based on field work performed during the summers of 1921 and 1922. The method of treatment departs somewhat from that used in the former numbers of this series. As the exposures on the Credit are farther from Toronto than the others referred to in this report, only those fossils which are new to science are treated in detail. This subject forms the second section of this number, the first being devoted to faunal lists, comments on important features, and the stratigraphic range of the species. The succession of strata and the correlation of the faunas is reserved for Part 6, but the necessary stratigraphic introduction precedes the paleontology in this number.
