There is a natural wonder near Viluppuram. At 20 miles from Viluppuram, is Tiruvakkarai where there is a fossil wood park. Many people who visit the famous Vakrakali temple and the Siva temple do not know about the fossil wood or stone tree park. I would suggest the Geological Survey of India who maintain the park place sign posts near the temple.

 

Tiruvakkarai has hundreds of fossilised trees spreading over a vast area—247 acres. The entry is free. It has got trees 20 million years old. They were washed away millions of years ago and buried under the earth. They are now wood stones. The department has installed big boards in Tamil and English explaining it to laymen. They have done a very good job. A watchman is getting the signatures of visitors on a note book, which must be appreciated.

 

There is another fossil wood park near Perambalur.

Scientists have found out the types of trees. Following are the facts given on the board at Tiruvakkarai:-

Fossilwood of Mesembrixylon schmidianum (gymnosperms/non -flowering plants)

Peuce schmidiana (angiosperms/flowering plants)

 

How big the trees are?

30 metres long with a diameter of 1-5 metres

 

How did the trees become stones?

During the petrification period, the organic matter inside the tree is replaced with silica/sand

 

How did they know they were washed away from another area?

Absence of roots and branches indicate toward in this direction.

Who discovered it?

In 1781 an Europena recorded the occurrence of it.

What is the use of preserving it?

These trees tell the age of the earth and the flora and fauna of an area.

Trees’ annual rings are preserved even in the fossilised wood.

They are of Mio-pliocene Sedimentary Rocks.

In some parts of the world they even indicate the drought, volcanic eruptions happened millions of years ago.
