Where: Aragón, Spain (42.3° N, 0.6° E: paleocoordinates 34.4° N, 0.5° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: La Posa Formation (Tremp Group), Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• also listed as Blasi Fm.; "levels are above the Abatomphalus mayaroensis zone" in Canudo et al. 1999

•The Conques Formation is equivalent to the "lower Red Garumnian" 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).

•Site is in the "Grey Garumnian" (Alonso et al., 2018), orig. correlated with chron C30n, but later with chron C29r

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils
