Middle Triassic (Ladinian) conodonts and cephalopod arm hooks from Hornsund, Spitsbergen

Jerzy Trammer


The conodonts Gondolella mombergensis mombergensisTatge, G. mombergensis media Kozur, and G. haslachensis trammeri Kozur, and cephalopod arm hooks have been found in the Middle Triassic (Somovbreen Member, Drevbreen Formation) of Hornsund area, Spitsbergen. The Somovbreen Mb. has been attributed to the Lower Ladinian (Fassanian) on the basis of the recognized conodonts. The Ladinian conodont fauna of Spitsbergen resembles its time equivalents from the German and North American bioprovinces.
