“…Based on the comparison with palynological assemblages of the Reiflinger Kalke (Grossreifling, Northern Calcareous Alps) and the occurrence of a Longobardian bivalve Daonella lommeli there (Mostler and Scheuring, 1974), Scheuring assigned a Longobardian (late Ladinian) age to the assemblages from Meride (Scheuring, 1978;Stockar et al, 2012). In the Global Boundary Stratotype Section and Point for the base of the Carnian (Prati di Stuores/ Stuores Wiesen, Italy), Vallasporites ignacii (Enzonalasporites ignacii Scibiorski et al, 2022) and Patinasporites densus in association with Enzonalasporites vigens are regarded as indicative for the base of the Carnian (Mietto et al, 2012). The genus Enzonalasporites occurs in Association C, whereas P. densus was recorded only from Association F onward (Scheuring, 1970).…”

Well-preserved Carnian (Late Triassic) palynomorphs are rare in Switzerland, despite sediments include one of the important plant fossil localities, Neue Welt near Basel. Modern detailed palynological studies on Triassic palynomorphs in general and especially in the Carnian are scarce, most palynological studies were carried out more than 50 years ago. Nevertheless (Late) Triassic sediments still yield surprises for palynological research. Here, we present the results of the re-study of the famous Belchentunnel samples that were studied and published by Bernhard Scheuring in 1970. The less cheerful result concerns the preservation of slides: more than 60% of the slides are degraded. On the other hand, the restudy of the well-preserved slides showed an unexpected number of algae, acritarchs, and spore taxa not described so far. Especially the spores facilitate the correlation with the well-known biostratigraphic schemes established for the Germanic Basin. The distribution of Porcellispora longdonensis throughout the Belchentunnel succession is especially striking. The acme just below the Schilfsandstein might suggest the presence of ephemeral ponds.
