The Víðidalur Formation (~ 1.7 Ma) is found in north‐western Iceland and consists of tillite, conglomerate, sandstone, siltstone and claystone. The macrofossil assemblage is dominated by Alnus aff. viridis and Polygonum viviparum but also includes B. nana × pubescens, Vaccinium cf. uliginosum, D. octopetala and Salix sp. The pollen and spore flora are species‐rich and include Pinus, Menyanthes, Myrica, Trollius, Fragaria and Sanguisorba. Overall, the fossil flora indicates forest‐tundra vegetation on uplands in the region.
