The Kokolik River mostly transects the mid and late Albian rocks assigned to the Kukpowruk Formation. The fossils represent pre-angiosperm forests dominated by conifers. Common leaf forms are assigned to Pityophyllum and Podozamites, ginkgophytes in the form of Sphenobaiera and Ginkgo and cycadophytes Nilssonia and Taeniopteris. |
