“…The only other fossil tracks ‘competing’ with MZM Ge 2028 and 2029 would be the lowermost Permian specimens from the upper part of the Ilmenau Formation in Germany (Voigt 2005, 2012; Lützner et al . 2012, 2020; Schneider et al . 2020) and from the Cape John Formation in Nova Scotia (van Allen et al .…”

Lower Permian strata of the Boskovice Basin in the Czech Republic have yielded hundreds of largely complete seymouriamorph individuals, some of which are exceptionally preserved and have noticeable soft tissues, such as external gills and eye structures. The vast majority of these finds are referable to Discosauriscus austriacus, and almost exclusively represent larvae and juveniles tied to aquatic environments. Only one of the specimens discovered to date has been interpreted as an early adult, although late juvenile and early sub‐adult stages have been proposed for it as well. Regardless, no other seymouriamorph adults have been reported from the Boskovice Basin so far. Here we present the first comprehensive assessment of seymouriamorph tracks and a trackway from the Asselian (lowermost Permian) of the Boskovice Basin. The morphology of the tracks is congruent with that of the ichnotaxon Amphisauropus and indicates an attribution to Discosauriscidae or that they belong to as yet unrecognized large seymouriamorphs. All tracks were made by individuals much larger than the largest discosauriscid known from bodily preserved material and are interpreted as those of adults tied to terrestrial environments, thus apparently documenting a habitat shift that occurred relatively late in the ontogenetic development of these seymouriamorphs. Furthermore, the largest track is preserved in extraordinary detail and includes soft part impressions such as digital, palmar and plantar flexion creases, making the specimen one of the best preserved seymouriamorph tracks described to date. Finally, one of the tracks originates from the lowermost Asselian and is therefore among the oldest known records of seymouriamorphs worldwide.

“…During earliest post-Variscan development at <305 Ma wide-spread intermontane Late Carboniferous-Permian fault bounded graben and half-graben basins, such as the NE-SW trending Saar-Nahe (Henk, 1993;Stollhofen, 1998;Boy et al, 2012) Saale (Ehling and Gebhardt, 2012), Kraichgau and Schramberg basins (Sitting and Nitsch, 2012) and NW-SE striking basins (e.g. Naab and Thuringian Forest basins) are formed (Paul and Schröder, 2012;Lützner et al, 2012). Compared to the Carboniferous, the Rotliegend is characterized by widespread intrabasinal volcanism and depositional areas became enlarged across the internal parts of the Variscan Belt, e.g.…”

Abstract. The Bohemian Massif exposes structures and metamorphic rocks remnant from the Variscan Orogeny in Central Europe and is bordered by the Franconian Fault System (FFS) to the west. Across the FFS, possible presence of Variscan units and structures are buried by Permo-Mesozoic sedimentary rocks. We integrate existing DEKORP 2D seismic reflection, well and surface geological data with the newly acquired FRANKEN 2D seismic survey to investigate the possible westward continuation of Variscan tectonostratigraphic units and structures, and their influence on latest to post-Variscan basin development. Subsurface Permo-Mesozoic stratigraphy is obtained from available wells and are tied to seismic reflection profiles using a synthetic seismogram calculated from density and velocity logs. Below the sedimentary cover, three main basement units are identified using seismic facies descriptions that are compared with seismic reflection characteristics of exposed Variscan units east of the FFS. Our results show that Upper Paleozoic low-grade metasedimentary rocks and possible Variscan nappes are bounded and transported by Variscan shear zones to ca. 65 km west of the FFS. Basement seismic facies in the footwall of the Variscan shear zones are interpreted as Saxothuringian basement. We show that the location of normal fault-bounded latest to post-Variscan Upper Carboniferous-Permian basins are controlled by the geometry of underlying Variscan shear zones. Some of these Upper Carboniferous-Permian normal faults reactivated as steep reverse faults during the regional Upper Cretaceous inversion. Our results also highlight that reverse reactivation of normal faults gradually decreases west of the FFS.
