The gallery exhibits a large collection of invertebrate fossil specimens mostly of extinct groups, arranged according to the Geological time scale. The key artefacts of this gallery include the earliest plant fossil from Gondwana land, followed by an egg of a Dinosaur, which was discovered in the Kheda district, Gujarat. A large mollusc fossil from peninsular India and a snake fossil impression discovered from Myanmar are the other highlights of the gallery. The gallery also houses Stromatolite – the earliest record of life found in India (3200 million years old).
