Stones and grit that are swallowed by birds collect in the gizzard and are known as gastroliths. The gizzard is where any undigested food that has not been fully broken down by the stomach and gastric juices ends up, and is pulverized there by the friction action of the swallowed stones, or gastroliths.

If birds are dinosaurs, then maybe there were humanoid reptilians that haunt us to present. Not serious about this.
