Coal pebbles found in 1994 in the Greham Bell Island (Franz Josef Land Archipelago) are made up of Barzas-type cuticular liptobiolith. The coal belongs to the initial stage of catagenesis and is characterized by high content of cutinite (up to 70%) with very low reflectance (Ro = 0.1%). Maceration products show some tegillate elements of Arthropoda and individual Devonian spores. It is supposed that plant cuticle and Arthropoda exocuticle are present in this coal. Obtained data suggest presence of Paleozoic rocks in the sedimentary sequence, although they are not yet recovered. These data complement available information on distribution of specific Devonian coals and allow to have a new insight into zoogenic material involved in coal formation.
