Barranc de Guixers-2 tracksite (Cretaceous of Spain)

Where: Cataluña, Spain (42.1° N, 1.0° E: paleocoordinates 34.1° N, 0.8° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Conques Formation (Tremp Group), Early/Lower Maastrichtian (70.6 - 66.0 Ma)

• lower red unit, C29r, 60 m below K/Pg boundary

•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).

• bed-level stratigraphic resolution

Environment/lithology: "channel"; lithology not reported

• "fluvial, meandeirng streams, channel facies"

Size class: macrofossils

Preservation: cast, trace

Collection methods: surface (in situ), peel or thin section,
