HIDDEN IN PLAIN SIGHT: REVISITING SOME KNOWN TETRAPOD TRACKWAYS OF THE WESCOGAME FORMATION (LATE PENNSYLVANIAN) OF GRAND CANYON NATIONAL PARK, ARIZONA, USA
Our measurements and descriptions of these trackways are based on photogrammetric 3D models generated from photographs taken within the park and its facilities. In all three cases, the trackways appear to have been created by similar animals walking in eolian sand. Sedimentary features associated with the in situ trackway suggest that the environment was humid. We tentatively refer these trackways to the ichnogenus Amphisauropus, which has been attributed to seymouriamorph reptiliomorphs.
