📄 Image slot — layered sandstone showing fossil traces against desert sky.
The Thar looks changeless and is anything but. The desert beneath your boots is the youngest layer of a very old story.
Three chapters you can see
- The sea: the region sat under a shallow Tethys sea for much of deep time; the Jurassic fossils at Akal preserve a humid coastal forest that later desert completely replaced.
- The rivers: dried channels and the Ghaggar debate mark a wetter era when rivers crossed what is now dune country.
- The wind: the current sand seas are wind-built, and still moving; the dune types guide shows the forms in motion today.
Where to look: the fossil park is the headline site, but cut road sections around the district show the layering too — your driver can point out good ones.
