“…The Late Devonian biocrises, the Kellwasser and Hangenberg events, primarily effected shallow marine ecosystems [57,58]. In the Late Devonian of Siberia, Kellwasser and Hangenberg facies are observed through the deposition of black mudstone and black limestones, and black shales, respectively [14,16,18,59]. Associated with these layers in various locations (and combinations) are bituminous deposits, effusive tuff, black siltstones, shales and mudstone [46].…”

Survivorship dynamics of the flora of Devonian Angarida

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.
