Some American Jurassic Ammonites of the Genera Quenstedticeras, Cardioceras, and Amoeboceras, Family Cardioceratidae

Description: Introduction: The interpretation of the data furnished by the study of these fossils has been hindered somewhat because the exact stratigraphic location of much of the material is unknown. It was gathered with regard merely for the general stratigraphic and geographic position. However, as a knowledge of the general relationship forms to those of other areas is in itself of value to the stratigrapher and systematist it has seemed desirable to describe and figure the species.
