Gastroliths are stones from a dinosaurs gastrointestinal tract. Stones would have been ingested by the dinosaur then retained in the muscular gizzard and used to help grind food down.

Such stones are identified by ensuring all three of the following are true: Firstly, the stone is unlike the rock found in its geological vicinity. Secondly, these stones are both rounded and polished from where they turned and tumbled around inside the dinosaur, and finally, these stones are found with the fossils of the dinosaur which ingested it. This provides enough evidence that these are genuine stomach stones.

ACTUAL AS SEENThe image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions.
