Where: Huehuetenango, Guatemala (15.6° N, 91.6° W: paleocoordinates 15.6° N, 91.6° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Upper Shaly Member (Chochal Formation), Kungurian (279.3 - 272.3 Ma)
• Ammonoid, fusulinid, and brachiopod correlations suggest similarity to "Leonard" of West Texas, specifically Skinner Ranch, Cathedral Mountain, and Road Canyon (Artinskian-Roadian). Collected from a limestone bed in the lower part of the shaly beds, about 50 m above the main limestone body of the Chochal Formation.
• bed-level stratigraphic resolution
Environment/lithology: marine; shelly/skeletal, black, gray, silty limestone
Size class: macrofossils
Preservation: replaced with silica
Collection methods: bulk, chemical,
• Several hundred pounds of limestone collected from both localities. Also includes verbeekinid fusulinids, trilobites, durhaminid and lophophyllid corals, ammonites, Mizzia, fish teeth, and fragments of vascular plants. It is not specified which of the two localities (USNM9257 or 9258) these occur at.
