“…In considering the biogeographic evolution of the Devonian-Carboniferous system, it should be noted that studies into the preservation potential of transgressive sequences have shown a positive relationship between transgression and taxic richness and diversity and the inverse for regression [35–37]. Within this study fossil flora during the Frasnian-Tournaisian was consistently observed within the basins of the southwest and more rarely upon the Angarida continent [16].…”

Devonian plants in Siberia present protracted pioneer succession. Research into the survivorship dynamics of early plant communities upon the palaeocontinent Angarida have demonstrated that transgression and volcanogenic nutrient influx were key to the survival of colonizing plants. Taxic proportions show that migrating taxa entered Angarida from the southwest, Kuznetsk and Minusinsk basins, dispersing across the continent in waves through central areas northwards. The patterns of dispersal are consistent throughout the Devonian. Increased nutrient load from the active pulses of the Viluy-Yakutsk Large Igneous Province, biogeomorphic ecosystem engineering and the increased biomass of Angaridan plants are assisted by Late Devonian transgression. These cumulative factors can be linked to the Late Devonian marine extinctions observed in Siberia.
