The gastrolith is a rock which is found in dinosaur stomachs to grind the food they had swallowed.
gastroliths are stones swallowed to aid digestion by an animal such as bird or dinosaurs.....
Chickens eat gravel for two reasons. Their lack of teeth means that food swallowed has to be processed by the stomach alone. The presence of gravel in the stomach helps to mash up the food in the stomach and ease digestion. Broken down gravel eaten by chickens is also used to form the hard shells of the eggs laid by hens.
Many species of birds will swallow stones. These aid in digestion because they help grind items in their stomachs. These stones are called gizzard stones or gastroliths and are usually smooth and round from the polishing action in the animal's stomach. When too smooth to do their required work, they may be passed or regurgitated.
To be frank, not much! Alligators spend most of their time sleeping, basking in the sun (something I wish I could do :)). They would then go into the water to cool off, and would find something to eat (usually a turtle or small mammal). Hi
Ostriches swallow pebbles that help as gastroliths.
They are called gastroliths.
rocks are called gastroliths

It has no teeth so it needs the stones as gastroliths to grind the food up in the ostrich's gizard.
These could all include the trace fossils. They would in things like gastroliths, coprolites, casts and molds, and imprints.
Sauropods, who were plant-eating dinosaurs, used rocks to grind their food to aid in digestion. These rocks are called gastroliths.

Herbivorous dinosaurs swallowed small stones called gastroliths if they didn't have strong grinding teeth to chew tough plants.
They were called gastroliths.
Fossils are classified into three. Here is the fossil type and example(s): cast fossils (filled in with molds), trace fossils (burrows, gastroliths, footprints), and true form fossils (real animal or real animal part).
