Moli del Baró-1 (Cretaceous of Spain)

Also known as Molí del Baró-1, Molí de Baró

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

• coordinate based on nearby landmark

• small collection-level geographic resolution

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

• Upper part of the ‘lower red unit’

•Talarn Formation; lower half of Chron C29r

•Previously assigned to the Conques Formation, 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: lacustrine - small; gray claystone

• Fluvial, meandering river environment; oxbow lake
• Fluvial sandstone and conglomerate bodies (meander point bar and channel infilling) are common

•facies F5B: "Claystones and siltstones / Grey / Laminated / Abundant plant remains and sulphide accumulations, limited lateral continuity"

Size class: macrofossils

Collected in 2002, 2007, 2020–2011
