In a groundbreaking revelation, scientists have unearthed compelling evidence of ancient wildfires dating back approximately 290 million years in the Wardha Valley coalfield of central India. This discovery, centered around macroscopic fossil charcoal fragments extracted from borehole AK-19 at a depth of 120 meters, offers a vivid glimpse into the fiery episodes that once scorched the prehistoric landscapes of Gondwana during the Early Permian period.

The charcoal fragments exhibit remarkably preserved cellular structures, including uniseriate and biseriate pitting patterns on tracheid walls, indicative of gymnospermous wood. Their pristine condition and substantial size suggest a par-autochthonous origin, implying that these charred remnants remained close to their source trees post-fire. Such findings not only underscore the prevalence of palaeo-wildfires in ancient India but also align with similar occurrences across the Gondwanan supercontinent .

This discovery adds a significant chapter to the limited records of palaeo-wildfires in India. Prior evidence was primarily confined to the Late Permian Raniganj Formation in the Damodar Valley Basin . The current findings from the Wardha Valley not only extend the temporal range of known wildfires but also enhance our understanding of the ecological dynamics and climatic conditions of the Permian era.

The presence of such ancient wildfires offers invaluable insights into the Earth's historical climate patterns, vegetation types, and atmospheric oxygen levels. Moreover, understanding these prehistoric fire events can inform current models predicting vegetation responses to climate change and fire regimes.

As researchers continue to delve into the geological archives, each discovery like this serves as a testament to the Earth's dynamic history, reminding us of the ever-evolving interplay between climate, vegetation, and fire through the ages.
