The fossilized logs at the site are estimated to be approximately 150 to 200 million years old.
The petrification process occurred when minerals replaced organic plant material, turning wood into stone over geological timescales.
The location is part of the larger Gondwana landmass geological sequence found in parts of eastern India.
The park was established to protect these remnants from illegal collection and mining activities in the region.
Local geological surveys suggest the presence of similar fossil beds throughout the surrounding forest patches of the Birbhum district.
Ilambazar Wood Fossil Park is a geological site located in the Birbhum district of West Bengal, India. It preserves significant specimens of petrified wood, some dating back millions of years to the Mesozoic era. The park serves as an open-air display where fossilized tree trunks are protected in situ within a forested landscape. It provides evidence of the ancient climatic conditions and vegetation that once existed in the Chota Nagpur Plateau region. The site is managed by the West Bengal State Forest Department to preserve the fragile fossilized remains from human interference and weathering. The area is characterized by its proximity to the Ajay River basin, which contributed to the geological conditions necessary for fossilization.
The main protected enclosures containing the largest, well-preserved horizontal petrified logs.
Wear comfortable, closed-toe walking shoes as the terrain can be uneven and sandy.
Bring mosquito repellent, as the park's wooded environment attracts insects.
Carry your own drinking water, as facilities within the park are limited.
Avoid visiting during the monsoon season as the paths can become waterlogged and difficult to navigate.
Maintain a respectful distance from the fossil displays and do not attempt to touch or remove any geological material.
