Arvind Gondaliya, a farmer, spotted the skin and hair in a farm near Muni Ashram around 3 pm and sounded off the department. The area from where the skin was found is located near Mandariya village, some three km from Visavadar.
Forest department officials rushed to the spot and seized wild animal's skin and hair. It has been sent for laboratory test at Sasan Gir.
Officials have launched a search for the carcass believing that the wild animal may have died a few days ago.
"The skin and other carcass will be taken to Sasan Gir for micro analysis and sent for forensic test to ascertain whether the remains are of lion or not,'' said Sandeep Kumar, deputy conservator of forests, Gir National Park and Sanctuary, Sasan-Gir.
Senior forest officials said they are investigating all aspects, including poaching, in this case.
"We can't rule out anything at this stage and investigating all the aspects. In some cases, lion die due to electrocution and farmer dispose of the body somewhere else and the skins and bones are found scattered," said a senior forest official.
