Development and research


Geologists have been aware of the fossils found in the present-day park area since the 1930s. People who have carried out research in the area include Mr. Auden (1933), Mr. Mathur (1958 and 1965), and Professor S. Kumar (1980–81). On 23 August 2001, the area was featured in an article written by journalist Vijay Shankar Chaturvedi for the Hindi newspaper Hindustan. Subsequently, it was formally inaugurated as a fossil park by District Magistrate Bhagawan Shankar on 8 August 2002.

An international workshop was organised in December 2002, attracting participation from 42 delegates from India and abroad. Canadian geologist H.J. Hoffman was impressed by the fossils, and remarked that he had not seen such "beautiful and clear fossils" anywhere else in the world. In 2004, researcher Mukund Sharma further explored the area.

In 2013, the state government sanctioned ₹12.5 million for the development of the Salkhan Fossils Park.
