Dinosaur Gastroliths

 

Dinosaur Gastroliths

The Image below is by Jordan Mallon showing a depiction of a sauropod dinosaur eating fronds and shoots. They also would have pulled out plants by their roots and with these would have been stones attached. It is often said that these stones were intentionally eaten by herbivore dinosaurs to aid their digestion. Gastroliths or stomach stones are often found near to a known dinosaur skeleton. When they are excavated they are slightly polished in nature (not from water or wind erosion) and smooth and this differentiates them from other stones that have not been in a dinosaur's stomach. Also the acid in the stomach would have had an effect and etched the surface of these stones.

Sauropod Dinosaur Gastroliths from the Morisson Formation, Denver, Colorado, USA. These are 150 Million years old.  Late Jurassic Age.
