Gastrolith (C/N) / (S/F)

Gastroliths are stones used in the digestion process by animals who lack proper teeth for chewing. When swallowed, these stones help crush the food in the stomach and are stored in a separate pouch (called a gizzard), hence the word “gizzard stones”.

Piles of gastroliths were found by Dr. Grant and Dr. Sattler, in the southern part of Isla Nublar, while they searched for a cause of the Stegosaur’s illness.
