Evidence of this theory was highlighted six years ago in the journal Palaeogeography, Palaeoclimatology, Palaeoecology.
At the time, the study’s authors found “macroscopic charcoal remains” that has been preserved over the millennia by volcanic ash.
They argued Antarctica’s wildfires were triggered by volcanic activity, caused by the movement of tectonic plates.
The study read: “The charred wood remains were identified as belonging to conifers, which were important components of the Antarctic palaeoflora during the Cretaceous.
“A review of the data published thus far regarding palaeo-wildfires in the Southern Hemisphere confirms that the charcoal remains analysed here are the first to verify the occurrence of palaeo-wildfires in the upper Campanian levels of the West Antarctic Peninsula.”
