A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, hair, petrified wood, oil, coal, and DNA remnants.
One similar type of fish-lizard fossil was found in Gujarat.Ichthyosaurs or ‘fish- lizards’ in Greek were large reptiles that lived at the same time as dinosaurs. While many ichthyosaur fossils have been found in North America and Europe, the fossil record in the Southern Hemisphere has mostly been limited to South America and Australia.
Guntupalli Prasad, a geologist at the University of Delhi, said when a fossil bone from the animal’s skeleton was first found by an Indo-German research team in Kutch in 2016, they suspected it to belong to a dinosaur. "But the bone was too long and later the whole skeleton was unearthed. It’s the first Jurassic ichthyosaur find in India".
