Les Llaus (LL) (Cretaceous of Spain)

Also known as Abella de la Conca

Where: Cataluña, Spain (42.2° N, 1.1° E: paleocoordinates 34.2° N, 0.9° E)

• coordinate estimated from map

• small collection-level geographic resolution

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

• 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

• bed-level stratigraphic resolution

Environment/lithology: coarse channel fill; bioturbated, red sandstone and fine-grained sandstone

• "point bars deposited in meandering fluvial systems...[and] crevasse splay and levee deposits."
• "lutites and thick sandstone beds...[with] thinner strata composed of fine-grained sandstone"

•facies F12B: "Mixed very fine- to coarse-grained sst, microcgl and cgl / Ochre and red / Lateral accretion surfaces, planar cross-bedding, current ripples / Purple, red and/or grey mottling, very bioturbated"

Size class: macrofossils

Collected in the 1990s

Collection methods: quarrying, mechanical,
