Where: Puebla, Mexico (19.3° N, 98.5° W: paleocoordinates 11.9° S, 47.0° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Late/Upper Pennsylvanian (307.0 - 298.9 Ma)
• STRATIGRAPHIC RELATIONS: From the Patlanoaya Fm AGE: Bursumian (Orenburgian) in text; placed here in Late Pennsylvanian to avoid stratigraphic orphaning. STRATIGRAPHIC POSITION: From near top of section.
• bed-level stratigraphic resolution
Environment/lithology: marine; lithified limestone
Size class: macrofossils
Collection methods: bulk, hydroflouric, sieve,
• PREPARATION METHODS: The methods of extraction are similar for the three samples, and all the microfossils have been extracted by etching with 5% hydrofluoric acid. COLLECTORS: Not stated, but presumably the authors. REPOSITORY: Laboratory of Palaeozoic Palaeontology and Palaeogeography (LP3) of the university of Lille (France); the field samples are emplaced in the laboratory of geology of the UNAM (Universidad Autónoma de Mexico, Mexico).
