“…The Łysogóry-Radom basin has been investigated for many years but mostly with a focus on the Łysogóry Block part (e.g. Narkiewicz et al 1998a, 1998b) and with particular emphasis on the Łysogóry Region of the Holy Cross Mountains (Czarnocki 1950; Szulczewski 1995; Malec and Turnau 1997; Narkiewicz et al 2006; Halamski 2009; Fijałkowska-Mader and Malec 2011; Filipiak 2011; Filipiak et al 2022; Malec 2012; Zatoń; and Wrzołek 2020). The Radom Area of the Łysogóry-Radom basin is known from only a few boreholes; despite the relatively low number of these boreholes, they were drilled to a considerable depth and have provided valuable lithostratigraphical and biostratigraphical data (e.g.…”

The Middle and Upper Devonian (Givetian and Frasnian) deposits of the Łysogóry-Radom and Lublin basins (south-central Poland) presented a diversified palynomorph assemblage. Numerous miospore taxa were documented and also contained well-preserved and varied plant remains, scolecodonts, acritarchs, chitinozoans, organic tentaculitoids, and bioclasts of uncertain biological affinity. Aneurospora extensa, Geminospora aurita, Samarisporites triangulatus and other documented taxa allowed us to establish two local miospore zones: the Givetian ‘Geminospora’ extensa zone and the Givetian–Frasnian Geminospora aurita zone. The time interval of these two zones shows the impoverishment in taxonomic diversity of microflora related to the rapid climate changes that are associated with the global Taghanic Event. The palynofacies analysis indicated a shallow-shelf environment with significant terrestrial input that was controlled by transgressive-regressive cycles, which confirmed the dynamic palaeoenvironmental changes. The new miospore taxon Retusotriletes radomskii is described.

The famous Martenberg section of the eastern Rhenish Massif, Germany, type-section of classical Frasnian goniatite and conodont zonations, has been restudied in order to document the microfacies development and to refine the conodont stratigraphy around the global semichatovae Event/Transgression, the proposed level to define a future upper Frasnian substage. More than 8.000 platform elements were identified and include new taxa. Palmatolepis jamieae is subdivided into the subspecies Pa. jamieae jamieae, Pa. jamieae savagei n. ssp., Pa. jamieae rosa n. ssp., and Pa. jamieae ssp. δ. Another new species, Pa. adorfensis n. sp., was previously partly identified as Pa. jamieae, while Pa. descendens n. sp. has previously been described in open nomenclature from Inner Mongolia. Morphotypes are defined in Icriodus symmetricus, Pa. ljaschenkoae, and Pa. proversa. A global literature survey shows that the eustatic semichatovae Event can be recognised in more than 20 regions of all continents with (sub)tropical Upper Devonian outcrops. At Martenberg, the transgression is preceded by a thin but distinctive interval with unconformities, microbial mats, sheet cracks, and currents that brought in the regionally youngest volcaniclastics. The new conodont data confirm that no typical Pa. jamieae (sensu the holotype) occur in the two beds originally supposed to represent the jamieae Zone in its reference section. We fully support the conclusion of Ovnatanova and Kononova (2020) that the jamieae Zone should be abandoned. Early Pa. jamieae subspecies and the related new taxa enter at Martenberg and in a few other regions in the globally easily recognisable Frasnian Zone 10 (= plana Zone). Frasnian Zone 11 (feisti Zone) is subdivided into subzones FZ 11a (= feisti Subzone) and FZ 11b (= nasuta Subzone). The base of the latter coincides with the semichatovae Transgression, the semichatovae Subzone of more shallow shelf settings, and is proposed to define in future the upper Frasnian substage base. On a global scale, the Martenberg section is currently the best bed-by-bed documented section for facies changes, conodont and goniatite biostratigraphy at the middle/upper Frasnian transition. Therefore, it is a prime candidate for a future GSSP selection. A global literature survey identified more than 20 other pelagic conodont successions that have the potential for precise correlation and a better understanding of the environmental changes associated with the semichatovae Event.
