Regurgitalite

Regurgitalites, or sometimes Regurgitaliths,^[1]^[2] are the fossilized remains of stomach contents that have been regurgitated by an animal, such as an owl pellet. They are bromalite trace fossils and can be subdivided into ichnotaxa. Regurgitaliths might provide useful information on the diet of the animal,^[3] but are difficult to relate to any particular species.^{[citation needed]}
