NATIONAL FOSSIL WOOD PARK, SATTANURDirection
Geological lstudy shows that more than 120,000,000 years ago, the sea (which lies today about 100 k.m. East of Sathanur) had transgressed as far as 8to 10 km West of Sathanur. During this period which is Geologically knownj as the cretaceous, the sea abounded in a variety of marine animals similar to those found in the present day sea. These animals, after death;, sank to the bottom and were buried by sands and clays brought down by the rivers. Along with them some of the trees which flourished on the seacoast or near shore were also buried after transport by flooded streams and were petrified in course of time.
The large trunk of petrified tree, which can be seen here, lies within the Trichirappalli group of rocks of about 100,000,000 years ago. This tree shows the presence of Conifers (The non flowering plants) that dominated the land vegetation prior to the advent of Angiospems (the flowering plants of the present of lday).
The petrified tree trunk at Sathanur measures over 18 meters in length Similar fossil trees measuning a few meters in length are found along the stream sections near Varagur, Anaipadi, Alundalipur and Saradamangalaml. Dr.M.S.Krishnan of the Geological Survey of India first reported this fossil tree in 1940.
