ichnofossil (plural ichnofossils)

   • 2007, Charles E. Savrda, “6: Taphonomy of Trace Fossils”, in William Miller, III, editor, Trace Fossils, Elsevier, page 106:

     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.

   • 2010, Eduardo S. Bellosi et al., “21: Ichnofacies Examination of the Sarmiento Formation”, in R. H. Madden, A. A. Carlini, M. G. Vucetich, R. F. Kay, editors, The Paleontology of Gran Barranca, Cambridge University Press, page 313:

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

   • 2017 March 22, Elsa Panciroli, “Walking in the footsteps of giants and gerbils: what fossil prints can tell us”, in The Guardian:

     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.
