Basis of coordinate:estimated from map
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
Stratigraphic resolution:bed
Stratigraphy comments: from the "Lower Red Garumnian"
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).
Now Chron C29r
