Abstract

Danish expeditions under the leadership of Lauge Koch have collected several ammonoids from the "Martinia beds" of Clavering Island, northeastern Greenland. The genus Cyclolobus, which is well represented, indicates that the fauna is younger than any other Paleozoic ammonoids known from the Western Hemisphere. The containing beds are assigned to the uppermost Permian and correlated with the upper Products limestone of the Salt Range in India.
