“…This hypothesis has been supported by several authors based on studies carried out in North America, Europe, and Asia (Brown et al, 2012;Scott et al, 2014). Other authors have also sought to find evidence of the occurrence of paleo-wildfires in southern areas of Gondwana (e.g., Martill et al, 2012;Abu Hamad et al, 2016;dos Santos et al, 2016;El Atfy et al, 2016;Lima et al, 2019). However, when considering the depositional strata of the end of the Cretaceous for austral areas, there is a significant lack of detailed data on the occurrence of paleo-wildfires, an information gap that has been an impediment to the adequate understanding of the paleoenvironmental characteristics during that period.…”

“Antarctic on fire”: Paleo-wildfire events associated with volcanic deposits in the Antarctic Peninsula during the Late Cretaceous

The occurrence of paleo-wildfire events during the Campanian age of the Late Cretaceous is demonstrated in this study for the first time with deposits from the King George Island, South Shetland Islands, Antarctic Peninsula. With the aim of providing information that fills important paleoenvironmental and paleobiogeographic gaps about the end of the Cretaceous for the Gondwana, samples of macroscopic charcoal were collected at two different volcanic levels of the Price Point outcrop, King George Island, during the expeditions to the Antarctic Peninsula by the Brazilian Antarctic Program (PROANTAR). The samples of charcoal were treated and later analyzed under a stereomicroscope and scanning electron microscope. The analysis allowed the identification of morphoanatomical structures with potential taxonomic affinity with Podocarpaceae. These conifers were important in temperate forests of high-latitude environments during the Late Cretaceous, and this is in accordance with previous palaeobotanical records from Price Point. The analysis also showed that southern paleofloras were subject to the occurrence of paleo-wildfires much more frequently than previously thought. This indicates that fire and active volcanism were significant modifiers of the ecological niches of austral floras, because even in distal areas, the source of ignition for forest fires often came from contact with a hot volcanic ash cloud, where the vegetation was either totally or partially consumed by fire.

Fire is a major driver for the evolution of biodiversity throughout the Phanerozoic and occurs in continental palaeoenvironments since the advent of the first land plants in the Silurian. The detection of palaeo–wildfire events can be based on different proxies, and charcoal is widely accepted as the most reliable evidence for such events in sedimentary layers. Although the identification of sedimentary charcoal as the product of incomplete combustion was the subject of controversial scientific discussions, palaeobotanical data can be used to confirm the pyrogenic origin of such material. In an overview on Palaeozoic and Mesozoic charcoal remains, differences in the number of published records can be detected for individual periods; including phases with both, lower (Silurian, Triassic, Jurassic) and higher (Devonian, Carboniferous, Permian, Cretaceous) numbers of published evidences for palaeo–wildfires. With the aim to discuss selected advances in palaeo–wildfire studies since the beginning of the 21st Century, we present an overview on the published occurrences of charcoal for an interval from the Silurian up to the Cretaceous. It was possible to confirm that a lack of detailed palaeobotanical data on the subject is detected in some intervals and regions, despite the high potential of occurrences detected in form of pyrogenic inertinites by coal petrographic studies. Although such temporal and regional gaps can be explained by taphonomic and palaeoenvironmental biases, it also indicates the scientific potential of future studies in diverse palaeogeographical and temporal settings.
