Early Permian trace fossils from the Abo formation near Jemez Springs, Sandoval County, New Mexico
— Spencer G. Lucas, [ed.]

Abstract—The first known tetrapod footprint assemblage from the Abo Formation in the Jemez Mountains is from New Mexico Museum of Natural History locality 10325, in a 1.3-m-thick bed of ripple-laminated sandstone about 44 m below the upper contact of the Abo Formation with the overlying De Chelly Sandstone of the Yeso Group. The footprints are associated with walchian conifer impressions, Supaia,and a low-diversity invertebrate ichnoassemblage dominated by Scoyenia but including Diplopodichnus, Palaeophycus, Planolites and cf.Sphaerapus. Most of the footprints are of temnospondyls (Limnopus). Rare footprints at the locality can be assigned to cf. Varanopus (captorhiniomorph reptile), cf. Amphisauropus (seymouriamorph) and Ichniotherium (diadectomorph). The occurrences of Amphisauropus and Ichniotherium are significant, as these ichnotaxa are only present in relatively inland localities of the Abo depositional system. The Jemez Springs footprint locality fits that, as it was far from the Abo-Hueco shoreline in southern New Mexico.
