Fossil wood, commonly referred to as petrified wood, is formed when plant material is buried under sediment. This process initially preserves the organic material due to a lack of oxygen, which prevents decay. Over time, the organic plant materials undergo a process of crystallization, transforming into stone while maintaining the wood's original structure.
In India, significant deposits of fossil wood can be found in the states of Rajasthan, Gujarat, and Jharkhand. The Thar Desert in Rajasthan is particularly renowned for its beautifully preserved petrified wood specimens.
The age of fossil wood found in India varies significantly. Some specimens date back to the Jurassic period, which is over 180 million years ago, providing a glimpse into the Earth's ancient past.
Fossil wood carries both scientific and cultural significance. Scientifically, it offers vital clues about the historical climate and vegetation of specific regions, assisting scientists in understanding environmental changes over the ages. Culturally, fossil wood is often crafted into jewelry and decorative items, appreciated for its unique and attractive appearance.
Yes, fossil wood is regarded as a geological treasure in India. The collection or trade of fossil wood without proper permissions is restricted under various laws designed to preserve the nation's natural heritage.
