Integrated Ladinian bio-chronostratigraphy and geochrononology of Monte San Giorgio (Southern Alps, Switzerland)

Palynological zonation and particulate organic matter of the Middle Triassic of the Southern Alps (Seceda and Val Gola–Margon sections, Northern Italy)

“…New radiometric ages from the Meride Lst. at Monte San Giorgio also fall within this time span and should correspond to levels of the MPV and the UPV (Stockar et al, 2012). Furthermore all these numeric age constraints are consistent with a recent very precise age of 237.77 ± 0.05 Ma for a volcaniclastic layer in the Wengen succession (Fernazza Fm.)…”

“…Correlated sections further afield include Val Gola near Trento, the GSSP of the base of the Ladinian stage at Bagolino (Lombardy) as well as the Anisian-Ladinian succession at Monte San Giorgio (southern Switzerland; Besano Fm.-Meride Lst. ; Brack and Rieber, 1993;Stockar et al, 2012). The ages attributed to the Buchenstein Fm.…”

“…Records include the classical studies of Van der Eem (1983) and Brugman (1986) but also newer work of Roghi (1997), , , Mietto et al (2012), and Stockar et al (2012).…”

A Middle Triassic pachypleurosaur (Diapsida: Eosauropterygia) from a restricted carbonate ramp in the Western Carpathians (Gutenstein Formation, Fatric Unit): paleogeographic implications

“…The photography of the fossil is from a D610 Nikon camera. The paleogeographic map was modified using modified data from several authors (Michalík & Kováč 1982;Häusler et al 1993;Michalík 1993Michalík , 1994Stampfli 1996;Diedrich 2009;Renesto 2010;Stockar et al 2012;Beardmore & Furrer 2016).…”

“…1 -dry land; 2 -epicontinental sea; 3 -carbonate platforms of the Alpine-Carpathian shelf; 4 -carbonate platforms of the Apulia shelf; 5 -Paleo-Tethyan oceanic basin; 6 -pachypleurosaurs and their possible migratory routes from Germanic basin to Carpathian basins (full red line indicates more presumable route than that of dashed line). Asterisk -indication of Monte San Giorgio locality with abundant fossil record of pachypleurosaurs in Southern Alps (see Renesto 2010;Stockar et al 2012;Beardmore & Furrer 2016). Hugi et al 2011), in contrast to other members of Sauropterygia that lived at the same time (e.g., Rieppel 2000; Klein et al 2015Klein et al , 2016b.…”
