Plant taphonomy and palaeoenvironment from the Upper Cretaceous of Isona, Tremp Basin, southern Pyrenees, Catalonia, Spain

Facies architecture and palaeoenvironmental implications of the upper Cretaceous (Santonian) Csehbánya formation at the Iharkút vertebrate locality (Bakony Mountains, Northwestern Hungary)

“…During this transport mechanical fragmentation and size reduction of plant debris did occur (Villalba-Breva et al, 2015). The small size seeds and fruits could better survive the transport or they may have originated from plants in the nearby floodplain, reasons, possibly explaining the so many well-preserved mesofossils found here.…”

Transitional environments of the lower Maastrichtian South-Pyrenean Basin (Catalonia, Spain): The Fumanya Member tidal flat

“…After the sedimentation of the Fumanya Mb, tidal influence persisted during the sedimentation of the Posa Fm. In this formation, the recurrent water salinity changes observed in (1) fauna, (2) isotopic values, (3) coal formation (freshwater indicator) and (4) plant communities (see also Villalba-Breva et al, 2015) indicate that in the Posa Fm a mosaic of subenvironments, such as lagoonal, freshwater lacustrine, mires etc., coexist. Towards the continent, the lagoon was bordered by a mudflat that led into an area of continental sedimentation with marshes (Nagtegaal, 1972;Liebau, 1973;Díaz-Molina, 1987;Cuevas, 1992;Ard evol, Klimowitz, Malag on, & Nagtegaal, 2000;L opezMartínez et al, 2000;Rosell et al, 2001;Oms et al, 2007).…”

The Molí del Baró-1 site, a diverse fossil assemblage from the uppermost Maastrichtian of the southern Pyrenees (north-eastern Iberia)

“…In this neighbouring locality, plant remains deposited in a distal floodplain and revealed some information about plant communities that grew up in the early Maastrichtian fluvial environments of the area. Based on plant megafossils and sporomorphs, Villalba-Breva et al (2015) suggested that a portion of leaves from South Isona were transported from a source riparian community composed of a likely member of Betulaceae with a diversity of ferns growing up in the understory. According to Marmi et al (2015) these differences may be due to the true composition of plant communities or taphonomic biases.…”

“…Remains of other vertebrates, such as fish (Kriwet et al, 2007), amphibians and squamates (Blain et al, 2010;Blanco et al, this volume), turtles (Marmi et al, 2012a), crocodylomorphs (Blanco et al, 2014, in press;Pu ertolas Pascual et al, 2014, this volume) and pterosaurs are also found in the same beds. Foraminifera, molluscs and ostracods (Liebau, 1973) as well as charophytes and vascular plants Vicente i Castells, 2002) have provided interesting palaeoecological and biostratigraphical data (Villalba-Breva and Martín-Closas, 2013;Díez-Canseco et al, 2014;Vicente et al, 2015;Villalba-Breva et al, 2015).…”
