**This stone was in a Dinosaur's Stomach**

Age - 146.8 - 156.3 Million Years Old (Jurassic Era)

Like some modern bird, Dinosaurs ate and used Gizzard stones in their stomach to aid in digestion, giving them a specific polish and easily identifiable when discovered alongside Dinosaur fossils. 

 

* Gastrolith *

A gastrolith, also called a stomach stone or gizzard stone, is a rock held inside a gastrointestinal tract. Gastroliths in some species are retained in the muscular gizzard and used to grind food in animals lacking suitable grinding teeth. In other species the rocks are ingested and pass through the digestive system and are frequently replaced. The grain size depends upon the size of the animal and the gastrolith's role in digestion. Other species use gastroliths as ballast. Particles ranging in size from sand to cobble have been documented.

 

* The Morrison Formation *

The Morrison Formation is a distinctive sequence of Upper Jurassic sedimentary rock found in the western United States which has been the most fertile source of dinosaur fossils in North America. It is composed of mudstone, sandstone, siltstone, and limestone and is light gray, greenish gray, or red. Most of the fossils occur in the green siltstone beds and lower sandstones, relics of the rivers and floodplains of the Jurassic period.
