A tunnel-like structure created by a burrowing animal and filled with soil material from another horizon is called?

Explanation:
A tunnel-like burrow that is later filled with soil from a different horizon is called a krotovina. This feature records bioturbation by a burrowing organism, with the fill material often differing in texture or color from the surrounding matrix, making the burrow visible as a distinct pocket within the soil profile. Caliche is a cemented calcium carbonate horizon, not a burrow fill. A mixture cavity and mammillated deposit are not standard terms for this type of trace.
