'''''Brasilichnium''''' is the name of fossilised mammaliamorph footprints dating from the Jurassic and Cretaceous. They have been identified from Brazil and western North America.<ref name=Lockley2011>{{cite journal |first1=M.G. |last1=Lockley |year=2011 |title=The ichnotaxonomic status of Brasilichnium with special reference to occurrences in the Navajo Sandstone (Lower Jurassic) in the western USA |journal=New Mexico Museum of Natural History and Science Bulletin |volume=53 |pages=306–315 |url=https://books.google.com/books?id=fugoCgAAQBAJ&dq=M.%20G.%20Lockley.%202011.%20The%20ichnotaxonomic%20status%20of%20Brasilichnium%20with%20special%20reference%20to%20occurrences%20in%20the%20Navajo%20Sandstone%20(Lower%20Jurassic)%20in%20the%20western%20USA.%20In%20R.%20M.%20Sullivan%2C%20S.%20G.%20Lucas%2C%20%26%20J.%20A.%20Spielmann%20(eds.)%2C%20Fossil%20Record%203.%20New%20Mexico%20Museum%20&pg=PA306 |access-date=30 October 2021}}</ref>

''Brasilichnium'' is the name of the footprints, identified by their shape, and not of the genus or genera that made them, which is as yet unknown but was likely a mammaliamorph with a semi-erect leg posture. Mammaliamorphs were ancestors of modern mammals.<ref name="DoraziPorchettiEtal2017">{{cite journal |last1=D'Orazi Porchetti |first1=Simone |last2=Bertini |first2=Reinaldo J. |last3=Langer |first3=Max C. |title=Walking, running, hopping: Analysis of gait variability and locomotor skills in Brasilichnium elusivum Leonardi, with inferences on trackmaker identification |journal=Palaeogeography, Palaeoclimatology, Palaeoecology |date=January 2017 |volume=465 |pages=14–29 |doi=10.1016/j.palaeo.2016.10.009|hdl=11449/173809 |hdl-access=free }}</ref>
