Local versus global effects on changes of fossil diversity: paleoenvironmental interpretation of Triassic faunas of the Balaton Highland (Hungary)

Influence of upwelling on the sedimentation and biota of the segmented margin of the western Neotethys: a case study from the Middle Triassic of the Balaton Highland (Hungary)

“…Triassic ammonoid fauna of the Balaton Highland reaches its highest diversity during the Late Illyrian and this conforms the global diversity curve as well (Vörös 2009(Vörös , 2014.…”

“…This resulted in studies on lithostratigraphy (Budai 1992), bio-chronostratigraphy of the Middle Triassic succession (Dosztály 1993;Góczán and Oravecz-Scheffer 1993;Kovács 1993;Kovács et al 1990;Vörös 1993Vörös , 1998 and reconstruction of the basin evolution (Budai andVörös 1992, 1993;Budai and Haas 1997;Budai and Vörös 2006). Diversity changes and paleoenvironmental significance of Middle Triassic ammonoids and other fossil groups were presented by Vörös (1996Vörös ( , 2002Vörös ( , 2009Vörös ( , 2014 and Vörös et al (2003).…”

“…Bed by bed collection of the P-11a trench yielded more than 500 specimens of 14 taxa (Vörös and Pálfy 1989). However, after a Middle Anisian peak, the diversity of this group decreased during the Late Illyrian in the Balaton Highland (Vörös 2009) probably in connection with a relative sea-level rise (Budai and Vörös 1993).…”

“…Bivalves show low diversity with seven taxa (Vörös 2009). However, they are very abundant locally in distinct horizons, forming Daonella and Posidonia coquinas (Fig.…”
