Found only in a few locations in Southern Montana. \u003c\/p\u003e\n\u003cp\u003eGeologists usually require more than a few pieces of evidence before they will accept that a dinosaur used a rock to aid its digestion. First, the stone must be unlike the rock established in its geological vicinity. Secondly, it should be rounded and polished because, inside a dinosaur's gizzard, other stones and fibrous materials, in a process similar to that of a rock tumbler, would have acted upon any genuine gastrolith. Lastly, the stone must be found with the bones of the dinosaur that ingested it. It is this last criterion that causes trouble in the identification, as smooth stones found without context can be dismissed as having been polished by water or the wind.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/Psittacosaurus_stomach_stones_large.jpg?v=1487976813\"\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Montana Man 5000","offers":[{"title":"Default Title","offer_id":51844282843416,"sku":"06MCC157","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1250\/0441\/files\/5U8A1571_00abc253-f300-4510-a479-a4569a405203.jpg?v=1774218757","url":"https:\/\/www.fossilageminerals.com\/products\/3-sauropod-dinosaur-stomach-stone-gastrolith-rock-gizzard-stone-coa-06mcc157","provider":"Fossil Age Minerals","version":"1.0","type":"link"}
