National Fossil Wood Park – Perambalur – Tamil Nadu – India.

National Fossil Wood Park, Sathanur is located in Perambalur District, in Tamil Nadu. This park is located within Sathanur panchayat and has a fossilized tree trunk, which was discovered in 1940 by renowned geologist Dr. M. S. Krishnan of the Geological Survey of India, who hailed from Tanjore. The petrified tree trunk is believed to be over 120 million years old, and is considered to be evidence for the presence of a sea during the Cretaceous period in this area. As part of the tourism development works, a fossil museum will be set up adjacent to the tree. The trees belong to conifers that dominated the land vegetation during the period. It is situated about 700 m north of the village which can be approached by NH-45 connecting Chennai with Tiruchchirappalli up to Siruvachur village. From Siruvachur an unmetalled road connects Sathanur village which is about 14 km eastward. This national park is open to public throughout the year.
