The fossil was discovered by geologist and paleoclimate researcher Dr Ritesh Arya during a family visit to the area. While examining sandstone outcrops, Dr Arya noticed unusual impressions embedded in the rocks, which he later identified as palm leaf remains belonging to the Lower Miocene Dharamsala Formation.The discovery has been scientifically authenticated by Dr Mahesh Prasad, Senior Scientist at the Birbal Sahni Institute of Palaeosciences (BSIP) in Lucknow. The fossil exhibits the distinct parallel venation characteristic of palm leaves. Because preserving such delicate leaf structures in sandstone is highly unusual, scientists consider the find particularly valuable for understanding the region's geological and climatic evolution."The fossil provides compelling evidence that the Himalayan region, which today experiences a cool mountain climate, supported lush tropical vegetation around 20 million years ago," Dr Arya said.

“Fossilised plants serve as natural records of ancient ecosystems, helping researchers reconstruct past environmental conditions and climate patterns,” he said.Dr Arya noted that 19th-century geologist Henry Benedict Medlicott had previously reported fossil plant remains from the Kasauli region, which first helped establish the area’s tropical past.Calling for immediate conservation measures, Dr Arya urged authorities to preserve the fossil in situ (at its original location) and develop the site as a geoheritage and geotourism destination. He emphasised that the locality holds immense educational, scientific, and tourism potential.“This finding assumes added significance on World Environment Day, as it highlights the connection between ancient climate records and contemporary concerns regarding climate change, biodiversity conservation, and environmental sustainability,” Dr Arya added.Several fossil palm specimens discovered earlier in Kasauli and Ladakh are currently preserved at the Tethys Fossil Museum in Dangyari, Himachal Pradesh. Describing fossils as invaluable archives of Earth's history, Dr Arya emphasised that protecting geological heritage was essential for understanding long-term climate change and preserving scientific knowledge for future generations.The Baisakhi Sale Plan offers an excellent value of 2 years of subscription + 6 months complimentary.If you proceed with this purchase, your current monthly subscription plan will be immediately cancelled.
