| 概要 |
This is a report of our biostratigraphical and paleontological study of Triassic ammonoids from the coastal area of Van Keulenfjorden, Wedel Jarlsberg Land in West Spitsbergen. Triassic ammonoids, 28 ...species of 17 genera, are described and their zones in Svalbard are discussed. They consist mainly of the Lower and Middle Triassic ammonites. The Upper Triassic ones are very rare in this area. Gyronites cf. plicatus is a representative of the Lower Scythian Vardebukta Formation in the Polahaugen section. The Lower Member of Botneheia Formation is correlated to the Lenotropites caurus Zone and "fossiliferous bed" associated with some species of Anagymnotoceras, Hollandites and Gymnotoceras of KORCHINSKAYA (1982, 1986). The Middle Member yields Proarcestes and Ptychites. In the Upper Member, occurs poorly preserved ammonite, Nathorstites？sp. A. Another species of Nathorstites sp. found in the lower horizon of Kapp Toscana Group is probably Carnican.続きを見る
