“…Fossil materials lack any N-containing pyrolysis products. The Miocene and Pliocene materials from Banks Island contain fewer pyrolysates as well as fewer overall products than their counterparts from the middle Eocene Axel Heiberg Island in Canada (Yang et al, , 2007Staccioli et al, 2002; and this study). The Banks Island material, however, yields more polysaccharide pyrolysis products than do the Clarkia Miocene fossils.…”

“…The major chemical data for the examined fossil barks have been listed together with those of a modern sequoia (Sequoia sempervirens) from Trento (Italy) in Table 1; for comparative purposes, the corresponding data for the bark found in layer "O" (Staccioli et al 2002) have been also reported. Hereafter, bark and layer of recovery will share the same letter.…”

“…Several Arctic fossil woods, 25-65 million years old, have shown partial or total loss of polyoses (Staccioli et al 1997). Two recently analysed barks, one more than 40000 years old and the other more than 45 million years old (Canadian Arctic region), have been shown not to have different degradation pathways compared to wood (Staccioli et al 1998c;2002). has been observed.…”

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 loss of polysaccharides led to materials exhibiting a marked cation exchange capacity, which is comparable to what is found for humus, the final product of diagenesis of the forest litter. Dichloromethane extracts from the barks invariably showed the presence of n-alkanes from C14 to C30, and terpenes such as cadalene, calamenene, fichtelite, sandaracopimarane, abietatriene, simonellite, diaromatic totarane, ferruginol, dehydroferruginol, and sugiol. The presence of phenol-diterpenes and/or diaromatic totarane was related to species belonging to Cupressaceae, Taxodiaceae and Podocarpaceae, in agreement with the recovery of trunks of metasequoia in some forest levels.
