Tetrapodium is an ichnogenus of fossil footprints found in the Etjo Sandstone and Omingonde Formations (Tetrapodium elmenhorsti) of Namibia.
[1] The Etjo Sandstone fossils were initially identified as rounded, featureless depressions presumed to have been made by a quadrupedal animal, but more recent examination in 2016 could not identify such tracks and concluded they are most likely non-biogenic features of the rock surface.
