Investigation on Fossil Barks from an Arctic Canadian Site Constituted by a Multiple Level Tertiary Fossil Forest 45 Million Years Old
Summary Barks from the litters of a multiple level Tertiary fossil forest from the Canadian Arctic were chemically examined and compared with coeval Arctic fossil woods. Degradation and diagenesis of the polysaccharides similarly occurred in barks and woods. However, unlike the fossil woods, the los...
