The park consists of nine enclaves, but only a small portion of the 247 acres (approx 1 square km) is open to the public.[7] Officials of the GSI believe the fossils were formed during massive flooding that occurred millions of years ago.[8] The park hosts about 200 fossilized trees. They range in size from {{convert|3|to|15|m|ft}} meters in length, some of which are up to 5 meters in width.[1] They are strewn and partially buried in the park grounds.[6] No branches or leaves remain on the fossilised trunks.[8] Scientists speculate that the trees did not originally grow at the site, but were transported before they had petrified.[8] M. Sonneret, a European naturalist, gave the first detailed account of the fossils in 1781.[2] Quality of the fossilsThe fossils are well preserved due to extensive petrifaction.[8] The trees' annular rings and pit structures are clearly visible, allowing their age to be determined by counting the rings.[8] GallerySee also
