“…The Moror A site is located in a bioturbated and bioclastic limestone bed showing evidence of desiccation, and the Moror B outcrop occurs in a micritic limestone, which is also bioturbated. Other sites in the Tremp Formation that contain sauropod footprints (Orcau-2, La Massana and Fumanya) have also been characterized as lagoonal [49], [50] with tidal influence [51]. All these lagoonal localities are found in limestones (lithofacies F2B facies of Riera et al [6]).…”

The Latest Succession of Dinosaur Tracksites in Europe: Hadrosaur Ichnology, Track Production and Palaeoenvironments

et al. 2013

A comprehensive review and study of the rich dinosaur track record of the Tremp Formation in the southern Pyrenees of Spain (Southwestern Europe) shows a unique succession of footprint localities prior to the end-Cretaceous mass extinction event. A description of some 30 new tracksites and data on sedimentary environments, track occurrence and preservation, ichnology and chronostratigraphy are provided. These new track localities represent various facies types within a diverse set of fluvial environments. The footprint discoveries mostly represent hadrosaurian and, less abundantly, to sauropod dinosaurs. The hadrosaur tracks are significantly smaller in size than, but morphologically similar to, those of North America and Asia and are attributable to the ichnogenus Hadrosauropodus. The track succession, with more than 40 distinct track levels, indicates that hadrosaur footprints in the Ibero-Armorican region occur predominantly in the late Maaastrichtian (at least above the early Maastrichtian–late Maastrichtian boundary). The highest abundance is found noticeably found in the late Maastrichtian, with tracks occurring in the C29r magnetochron, within about the latest 300,000 years of the Cretaceous.

“…71 Ma for the Hippurites radiosus horizon in the Tremp and Ager basins. Charophyte biozonation (Villalba-Breva & Martín-Closas, 2011) and a Peckichara cancellata biozone were reported on top of the Fumanya Mb, both in the Vallcebre and Ager successions (within La Massana and Posa Fms, respectively). For the Tremp Basin, Villalba-Breva and Martín-Closas (2013) reported the Septorella ultima biozone (Riveline et al, 1996) that partially correlates with the Peckichara cancellata biozone (see discussion in Vicente, Martin-Closas, Arz, & Oms, 2015).…”

“…In addition, Cretaceous homogeneous populations of porocharacean charophytes, as those observed in some sequences of this association, are commonly interpreted as developed in brackish-water coastal conditions (Martín-Closas and Grambast-Fessard 1986;Mojon 1989;Schudack 1993;Climent-Domenech et al 2009;Villalba-Breva and Martín-Closas 2013). These facts indicate that the water bodies where these facies were deposited had variable influence of both freshwater and seawater, developing fresh, brackish, or near-marine salinity.…”

Coastal wetlands are prominent modern environments widely studied in geomorphology and ecology, but the term ''coastal wetland'' is still barely used for the sedimentological classification of ancient deposits. The depositional system studied here (Leza Formation, Cameros Basin, Early Cretaceous, N Spain) includes diverse carbonate and clastic facies deposited at the sea-land transition, and is an illustrative example of the wide array of sedimentary environments that may occur in coastal wetlands systems. The studied system was composed mainly of carbonate water bodies whose salinity ranged from fresh to brackish and near-marine, and which had variable input of clastic material due to their lateral connection with alluvial fans. In addition, the system also included carbonate water bodies with stronger marine influence, tide-influenced oolitic areas, and relatively restricted evaporative settings.
