Ichnofossil

For example, an ichnofossil might be the preserved track an animal, or its burrow.

Suites of taphonomic factors that influence body fossils and ichnofossils are clearly not identical. Nonetheless, without too much twisting, ichnofossil-lagerstätten can be placed into the same genetic categories.

The only abundant ichnofossils are large and inclined structures in La Cancha Bed (Profile K), interpreted as mammal burrows.

Changes in the preservational environment in the thousands or millions of years between the creation of each set of prints results in these different forms of ichnofossil.
