Get this from a library. The foraminiferal genus Orbitolina in North America; a study of the genus Orbitolina, its type species, morphology, and stratigraphic and geographic distribution in North America. [Raymond C Douglass; United States.

Department of the Interior.; Geological Survey (U.S.)]. The foraminiferal genus Orbitolina has been useful as an index fossil in the Cretaceous rocks of the circumglobal equatorial belt for nearly a century.

In Europe and the Near and Middle East enough work has been done on the species to allow their use for approximate correlations within the Cretaceous foraminiferal genus Orbitolina in North America book rocks. The study of American specimens of Orbitolina, had been almost neglected.

A set of specimens from Callovian glacial erratics found in gravel pits north of Berlin are provided by Steffen Schneider. We photographed and identified 34 specimens so far. Foraminifera typically produce a test, or shell, which can have either one or multiple chambers, some becoming quite elaborate in structure.

These shells are commonly made of calcium carbonate (CaCO 3) or agglutinated sediment particles. O species are recognized, both living (10,) and fossil (40,).

They are usually less than 1 mm in size, but some are much larger, the largest (unranked): SAR. The genus Petalodontia was proposed in by Pocta forCenomanian rudists from Bohemia, and in the same year Horiopleura was defined by Douville for Aptian-Albian faunasfrom Spain and SW France.

Subsequently Douville () applied Petalodontia Pocta to “Hippurites” calamitiformis defined earlier byBarcena () and to the new species P. felixi, both from se, Palmer ( The Foraminiferal Genus Orbitolina in North America,Professional Paper Archeogastropoda, Mesogastropoda, and stratigraphy of the Ripley, Owl Creek and Prairie Bluff formations,Professional Paper A.
