The occurrence of Silurian strata in White and Notre Dame bays and the Exploits Valley has been known since the explorations of Murray and Howley more than sixty years ago. These explorations, reconnaissance in nature, yielded little information concerning thicknesses, lithological characters, and faunal contents of the sedimentary rocks. The few Silurian fossils reported were of such general or uncertain identification as to have little value for precise age determination and specific correlation. It was not until 1910, when Charles Schuchert examined the collections of the Geological Survey of Newfoundland at St. John's, that the fossils were more definitely identified and the stratigraphic position of the fossiliferous Silurian strata of Newfoundland was somewhat more exactly determined.

Since the Silurian strata of northern Newfoundland are the most eastern known on the North American continent, the contained fossils are of paramount importance for correlation with the European Silurian. The meager information . . .
