Location description

In Northwestern Island, in the Mókollsdalur valley, there is a gully named Hrútagil. In this gully, Miocene sedimentary rocks rich in plant and insect fossils are outcropping.

The deposits in Hrútagil are part of the 8-9 million year old Skarosströnd-Mókollsdalur Formation. This formation is exposed at the southeastern part of Icelands Northwestern Peninsula, and can be traced along the Skarosströnd coastline, over the highland, and down into Mókollsdalur and towards the Kallafjördur bay.

In total, this formation has a stratigraphic thickness of over 120 meters. The lowest part of the Hrútagil section is composed of thick hyaloclastite units intercalated with several sandstones and breccias. The middle part mostly consists of sand- and siltstones. In the uppermost part, which consists of siltstones, claystones and organic-rich sediments, fossil plants and insects can be found. These layers have been deposited in a freshwater lake within the caldera of a volcano
