Dinosaurs swallowed stones as digestive pills more than 6.5 crore years ago in the Narmada Valley, a researcher has said.
Apart from eggs, fossils of the extinct dinosaurs we have recovered have 120 small shining stones of 2.5 diametre, in neighbouring Dhar district, Mangal Panchayatan Parishad chief Vishal Verma said today.
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 the 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.
The researcher said the female dinosaur used to lay eggs in the sand.
The common impression that dinosaurs took ample food was not right. Their eating habit was alike pythons, cold blood and slow metabolism.
