A deep well drilled by Shell/Esso some 100 km NE of the Shetlands was partly cored and yielded identifiable ammonites of two age-groups: Upper Oxfordian and Bathonian. The former consist of Amoeboceras as found both in Britain and the Arctic. The latter include Cranocephalites, Arcticoceras and Kepplerites identical in form, facies and sequence with those from East Greenland, constituting the most southerly record so far of the Boreal Middle Jurassic faunas so widespread in the Arctic but unknown in Britain and the rest of epicontinental Jurassic Europe.
