Bromalites are the fossilized remains of material sourced from the digestive system of organisms.
However, other types are recognised, including: regurgitalites (fossilized remains of vomit or other regurgitated objects such as owl pellets); cololites (intestinal contents); and gastrolites (stomach contents).
Whilst coprolites and regurgitalites are often difficult to tie to a specific producer, all bromalites potentially provide important and sometimes unique evidence concerning diet and other trophic factors.
