About the Omeisaurus

The best protection this dinosaur had against its carnivorous rivals was its enormous size. As long as Omeisaurus remained healthy, it was unlikely to be attacked. Like most other herbivorous dinosaurs, Omeisaurus spent most of the day eating. Each day he ate as much as several hundred pounds of plants. Because of this, he had no time to chew and swallowed the food whole and stones in his stomach caused the plants to be crushed.
