Also known as Blasi 1.5
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: La Posa Formation (Tremp Group), Late/Upper Maastrichtian (70.6 - 66.0 Ma)
• lower part of formation, "equivalent stratigraphic position" to Blasi 2; 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 in thee "Grey Garumnian" = La Posa Fm.

Environment/lithology: lagoonal or restricted shallow subtidal; gray marl
Size class: macrofossils
