This herbivore swallowed gastroliths (gizzard stones) to help break down the food in its stomach.

One indigenous person also implied that the gizzard stones of the pigeon may have had value locally.

A gastrolith, also called a stomach stone or gizzard stones, is a rock held inside a gastrointestinal tract.

This is known to be incorrect, as they swallowed their food whole and it was broken down by gizzard stones (gastroliths).

When found in association with fossils, gizzard stones are called gastroliths.

The finding of the heap of gizzard stones must have left a greater mark upon him that he had thought at first.

In the light of the lantern, he saw the gizzard stone, where he had left it on the desk top the night before.

It was presumed that dinosaurs swallowed their food whole and let the gizzard stones break down the plant fibers.

At least two specimens have been found with gizzard stones in the stomach cavity, the first ever reported for any pterosaur.

So far, no fossil of Plateosaurus has been found with gastroliths (gizzard stones) in the stomach area.
