A physics teacher, Verma said his parishad was doing research work for the last couple of years in Narmada Valley and they have come across evidences that dinosaurs swallowed small stones as digestive pills.
Toothless birds, too, swallow pebbles for digestive purpose. The stones hit each other and facilitate food grinding process, Verma said.
The herbivorous dinosaur used to swallow special type small stones to digest food, Verma said, adding these animals were 20-30 feet tall.
The dinosaurs` mouth used to be too small compared to their body. Their teeth also wasn`t too long following which chewing was tough practise for them, he said.
