SALAMANDER TRACKS (AMBYSTOMICHNUS?) FROM THE CATHEDRAL BLUFFS TONGUE OF THE WASATCH FORMATION (EOCENE)
VERTEBRATE TRACKS are comparatively rare in Tertiary deposits of the western United States. Unlike the deposits of the Mesozoic in this region, in which each formation often has several dozen known tracksites, there are only a few known sites in Paleocene units of the region (Lockley and Hunt, 1995)...
