Vardebukta Formation

The Vardebukta Formation is divided into the Urnetoppen Member and the overlying Wibebreen Member. Both members are of marine origin. They were deposited in a sublittoral to shallow-neritic environment. The top of the Urnetoppen Member contains the so-called Brevassfjellet Myalina beds, a 5–6 meter thick, fossiliferous conglomerate. Wibebreen Member The Wibebreen Member is ca. 90–100 meter thick in the Hornsund area. It consists of black to light-grey coloured shales, marly shales, arenaceous marls and siltstone. The lower part of this member contains mainly siltsone layers. The locally developed Skilisen Retzia Limestone belongs to the uppermost part of the Wibebreen Member. The Wibebreen Member is overlain by the Smithian (early Olenekian) aged Lusitaniadalen Member (="Sticky Keep Member") of the Vikinghøgda Formation. ==Paleobiota==

Fossiliferous layers of the Vardebukta Formation are concentrated to the uppermost part of the Urnetoppen Member (Brevassfjellet Myalina beds). These Dienerian aged beds have yielded the bivalves Myalina and Anodontophora, crinoids, conodonts, numerous isolated fish remains, and trace fossils. Fish The isolated fish teeth of bony and cartilaginous fishes have been described from the Brevassfjellet Myalina Bed (upper Urnetoppen Member of the Vardebukta Formation) of Hyrnefjellet, Hornsund. The bony fish teeth are mostly tentatively referred to Saurichthys sp.{{cite journal |last1=Błażejowski |first1=Błażej |last2=Duffin |first2=Christopher J. |last3=Gieszcz |first3=Piotr == See also ==
