Journal of Sedimentary Research (2013) 83 (12): 1202–1215.
.... Among the earliest thick phytodebris accumulations known, the occurrences lie within Pragian strata of the Val d'Amour Formation and Emsian strata of the Campbellton Formation of northern New Brunswick, and were deposited in low-energy wetlands where they were rapidly buried. Although the coaly shales...

... (but not earliest) Homerian-?earliest Gorstian age. Palynological preparations from core 11 are dominated by spores (cryptospores and rare trilete spores). Phytodebris, in the form of tubular structures, is also usually present but is not particularly abundant. Acritarchs and chitinozoans are almost invariably...

..., cryptospores and phytodebris. This type of palynofacies indicates an offshore environment ( Dorning, 1981b and Tyson, 1995 ). The rare land-derived taxa are decreasing down-hole indicating an increasing distal environment downwards. Previous reports ( Le Hérissé et al., 1995 ; Al-Hajri and Paris, 1998...

... along with abundant phytodebris, especially tubular remains (nematoclasts, sensu Gensel et al. 1988), which although of unknown systematic affinity are universally agreed to be terrestrial in provenance. The samples from the lower part of the section, which contain Moyeria , are dominated by well...

The succession has been reported to contain plant macrofossils ( Murašov and Mokin 1979 ), but only comminuted carbonaceous phytodebris was witnessed in this study...

... of palynological assemblages, which are dominated by thin translucent particles of detritus and phytodebris strongly affected by destruction ( Fig. 4 ). As noted above, the beginning of the Volgian transgression in the Olenek section was marked by deposition of the basal member of the Buolkalakh Formation...
