Macroscopic charcoal is widely accepted as a direct indicator for the occurrence of palaeo-wildfires. In Upper Paleozoic sediments of Euramerica and Cathaysia, records of these remains are relatively common and (regionally and stratigraphically) more or less homogeneously distributed in terrestrial sequences. On the other hand, just a few records have so far been published for the Permian of Gondwana and only recently it has been demonstrated that macroscopic charcoals are also common there. Most of the Late Paleozoic charred wood coming from that area have gymnospermous taxonomical affinity and has been reported from coal-bearing strata. It was also shown that the occurrences are spread out in different sequences and also in distinct stratigraphic intervals [e.g. Paraná Basin (Sakmarian/Artinskian of Brazil), Karoo Basin (Artinskian of South Africa), Damodar Basin (Lopingian of India) and Dead Sea region (Changhsingian of Jordan)]. However, a lack of data and comparative analyses (e.g. with the Northern Hemisphere occurrences) of macroscopic charcoal persists for the Gondwana, and detailed studies are necessary. In this context, the present project aims to study the Late Palaeozoic Gondwanan palaeo-wildfire occurrences using macroscopic charcoal as direct evidence. A comparative evaluation between the Gondwanan and Euramerican remains will be made to contribute to the improvement of palaeoenvironmental concepts about these events on a continental and global scale for that period. To reach this objective, mutual cooperation and international mobility actions between the host and the applicant will be necessary, justifying the here presented project to support the Capes-Humboldt Research Fellowship for Experienced Researcher grant.
