The Tethyan larger foraminiferal genus Orbitolina has been found in the easternmost part of the western North Atlantic continental shelf at 46°30'N. All other known occurrences of the genus in North America are south of 33°N. The species is Orbitolina conoidea Gras; its abundance in a grainsupported limestone indicates a tropical neritic environment and precludes the influence of Arctic waters in the Flemish Cap region in Early or Middle Cretaceous times.
