Part II: Paleontology
Published:January 01, 1938
The faunas of the Romaine and Mingan formations are not unlike in general appearance, but there do not seem to be any common species. Fossils in the Romaine formation are generally scarce and poor, but the surfaces of some beds in the lower half contain occasional low-spired gastropods and toward the top on Eskimo Island are strata in which Raphistomina laurentina is common; likewise, on the west side of Large Island there is a bed near the top in which Bathyurus romainensis is common. Intensive collecting probably would bring forth a large fauna from the Romaine formation, most species of which would be represented by few individuals, but to the present only 37 species have been collected, most of which are represented by a single or only a few specimens.
Some strata of the Mingan formation are replete with fossils, many of which are in an excellent state of preservation. The lower 30 to 40 feet contains certain beds that are essentially fossil coquinas, and good specimens may occasionally be found. A bed near the base not uncommonly is a mass of Camarotoechia orientalis, and on the south end of Mingan Island in some beds there are numerous Rhynchocamera varians. Camarotoechia pristina, Stylaraea parva, and other fossils. Ordinarily the beds containing Camarotoechia orientalis have the valves separated and crushed as in Trilobite Bay, on the west side of Clearwater Point, and on Eskimo Island, but on Parroquet Island the two valves are usually together and the shells are . . .
