Coordinates:	42.3° North, 0.7° East (view map)
Paleocoordinates:	34.3° North, 0.6° East
Basis of coordinate:	based on nearby landmark
Geographic resolution:	small collection

Time

Period:	Cretaceous	Epoch:	Late/Upper Cretaceous
Stage:	Maastrichtian	10 m.y. bin:	Cretaceous 8
Key time interval:	Late/Upper Maastrichtian
Age range of interval:	72.10000 - 66.00000 m.y. ago

Stratigraphy

Geological group:	Tremp	Formation:	Conques
Local section:	Areny	Local bed:	58 m
Local order:	bottom to top
Stratigraphic resolution:	bed
Stratigraphy comments: 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).
