Palaeoburrow

The general configuration of the palaeoburrows comprises vertical shafts showing branching.

Several tunnels, discovered over the past several decades, are interpreted as palaeoburrows built by fossil mammals, based on morphological patterns, transgressive boundaries in relation to the sedimentary units, and the presence of tracks on the walls and roofs.

Proposed size types for crotovines and palaeoburrows found in the Pliocene to Holocene outcrops of south a merica according to their maximal transverse diameters.
