Also known as Blasi 2a, 2b
Where: Aragón, Spain (42.3° N, 0.7° E: paleocoordinates 34.3° N, 0.6° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Abathomphalus mayaroensis foram zone, La Posa Formation (Tremp Group), Late/Upper Maastrichtian (70.6 - 66.0 Ma)
• lower part; 6.5 m interval; upper part of chron c30n, 65.6-68.7 mya
•The Conques Formation is equivalent to the "lower Red Garumen" facies. The Conques Formation was previously assigned a late maastrichtian age (Sellés and Villa 2015; Villa et al. 2015) Biostratigraphy and Sr stable isotope geochemistry suggest that the La Posa and Conques Formation are entirely early Maastrichtian, lying within chron C31r (see Caus et al. 2016; Oms et al. 2016; Fondevilla et al. 2016; Fondevilla et al. 2019).
•Actually the "Grey Garumnian" = La Posa Fm.
• bed-level stratigraphic resolution
Environment/lithology: lagoonal or restricted shallow subtidal; lenticular, gray marl
Size classes: macrofossils, mesofossils
Collection methods: bulk, sieve,
• includes seven types of eggshell
