Where: Aragón, Spain (42.3° N, 0.7° E: paleocoordinates 34.3° N, 0.6° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Conques Formation (Tremp Group), Late/Upper Maastrichtian (70.6 - 66.0 Ma)
• lower part of formation, 70 m above Blasi 3; base of chron c29r, ca. 65.6 mya
•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).
