Fossils are the dead remains/evidence of past organisms. Burrows, footprints & poo can also be preserved as #fossils.
#India has a legacy of ancient marine creatures, dinosaur bones/eggs & rare hominin (modern human) fossils.

#FossilFriday thread on some of India's relics:
1. Petrified forests, Thiruvakkarai & Sathanur, Tamil Nadu
The word 'petrified' means turn to stone.
~20 million years ago/mya these tree trunks were submerged in a swamp & their cellulose was replaced by silica - a rock forming mineral.

2. Near Dholavira, Kutch, Gujarat
I was lucky to access this #fossil park during my Masters (not always accessible as it lies close to the border)
Some petrified logs & dinosaur eggs lie metres away from the salty stretches of the Rann of Kutch.

Kutch region, Gujarat & Zanskar valley, Kashmir have #fossil of ancient marine creatures.
Trilobites, ammonites, molluscs & other vertebrates abound.
In #Nepal, the Kali Gandaki gorge is famous for 'shaligrams' - dark, river-smoothened, #fossil-bearing rocks.

Ironically, while Hinduism believes 'shaligrams' represent Lord Vishnu, creationists say #fossils were placed to test Man's faith in God 
Yet more fossil finds & better dating technology indicates that life did indeed 'evolve' from the oceans & onto land.

How do we know this? #Stromatolites!
Stromatolites are fossil colonies of ancient cyanobacteria - the earliest adaptation of single-celled microbes, that evolved at the interface of ocean & land.
from the book Indica, Pranay Lal
#MustRead: pg 40-47 on stromatolite formation.

Apart from parks (I won't list them, just Google), one can find #fossils in the most unexpected places: monuments!
Like this fossil fern at the base of the #Sanchi stupa, #MadhyaPradesh.
Or a petrified log at the temple near Qutb Minar, Delhi.

It seems, the Hazara Ram temple in Hampi also has a few fossils (can anyone confirm? I should keep an eye out on my next visit).
Would love to hear of other examples too!
Lamentably, in #India, we have little value for our #fossils, fossil sites, or #geoheritage.
