Vertebrate paleontology and biochronology of the lower Chinle Group (Upper Triassic), Sante Fe County, north-central New Mexico
Adrian P. Hunt and Spencer G. Lucas

Abstract:

Three Upper Triassic stratigraphic units in southeastern Santa Fe County, the Los Esteros and Tres Lagunas Members of the Santa Rosa Formation and the Garita Creek Formation, produce abundant fossil vertebrates. The Lamy amphibian quarry (Gunter bonebed) is in the Garita Creek Formation. The Los Esteros fauna is Adamanian in age based on the presence of Rutiodon, Desmatosuchus and Stagonolepis, and the Garita Creek fauna is Revueltian in age based on the presence of Typothorax. The Tres Lagunas fauna may be Adamanian or Revueltian.
