Where: Tamaulipas, Mexico (24.9° N, 98.2° W: paleocoordinates 25.6° N, 94.3° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Guajalote Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• LITHOSTRATIGRAPHY: From the Guajalote Fm, for which lithostratigraphic relationships are not discussed; correlated with the Tuxpam (or Tuxpan) Formations of southern Mexico, and have also been called San Rafael and San Fernandao Formation (Dumble's nomenclature); field relations indicate that the fossiliferous beds of the Guajalote Formation lie some 2,500 feet above those of the upper Oligocene. AGE: Early Miocene, on the basis of macrofossil biostratigraphy. STRATIGRAPHIC RELATIONS: From unknown position within formation.

• formation-level stratigraphic resolution

Environment/lithology: marine; lithified, shelly/skeletal sandstone

Size class: macrofossils
