The Triassic cephalopod genera of America The Triassic cephalopod genera of America

The marine Triassic section of .America is unusually complete, and its thickness compares favorably with that of any other region. All three subdivisions-Lower, Middle, and Upper Triassic--are represented by calcareous deposits, aggregating approximately 4,000 feet in thickness. Of this amount, about 800 feet belong to the Lower Triassic, about 1,000 feet to the Middle Triassic, and...
