The dark pelbiodetrital limestone beds of the ‘upper dark interval’ in the Koněprusy area, Central Bohemia, the Czech Republic, the assumed manifestation of the Kačák Event in this area, yielded a moderately diverse faunule of rhynchonelliform brachiopods and trilobites. In total, 15 species have been recognized (13 brachiopods and 2 trilobites), but the majority of them are only tentatively determined to generic level due to fragmentation, rarity or poor preservation. Brachiopod genera Leptaenopyxis, Protodouvillina, Douvillinella, Holynetes, Poloniproductus, Iridistrophia, Mystrophora, Pentamerella, Quasidavidsonia, Carinatina, Mimatrypa, Leptathyris, Eoreticularia and a single trilobite Astycoryphe were determined. The mode of preservation indicates transport of skeletal bioclasts from shallower parts of the basin and their fragmentation in debris flows together with fragments of terrestrial plants, crinoid detritus and numerous pelagic fossils, especially the dacryoconarid Nowakia ex gr. otomari. Associated conodonts (as well as trilobites) indicate a late Eifelian age for the fauna (Polygnathus ensensis Zone).

The lower Silurian strata of the Prague Basin, as well as in many other regions, are primarily represented by black shales, with limited to no record of benthic life. In this paper, we describe an exceptional late Aeronian volcanic-carbonate succession from the Hýskov locality near Beroun, which contains a diverse and well-preserved fossil assemblage and specific microfacies features. The studied section is mostly represented by well-washed, poorly sorted skeletal grainstones, rudstones and floatstones along with volcaniclastic material. The environment is interpreted as agitated, above storm wave base, and with rapid sedimentation and burial. The collection of acid-resistant microfossils includes abundant scolecodonts, conodonts and chitinozoans, of which only the chitinozoans have previously been studied. The scolecodonts recovered represent at least 14 polychaete genera and 20 species. The fauna bears a great similarity to the early Silurian assemblages previously reported from Baltica, and some environmentally sensitive species allow constraining the assemblage to shallow-shelf settings. The recovered conodonts similarly show close affinities to Baltic faunas, and suggest a Rhuddanian – Aeronian age for the studied section. The chitinozoan assemblage, containing at least eight species, is dominated by Conochitina, and most likely belongs to the C. alargada Biozone.
The holotype of the “archaeobatrachian” (i.e., non-neobatrachian) frog Eodiscoglossus santonjae Villalta, 1954 is redescribed herein, with focus on some features that have been misinterpreted. The specimen is articulated and poorly preserved as fragmentary bones and impressions, and is from the Early Barremian La Pedrera de Rúbies Lithographic Limestones Formation at Santa Maria de Meià, Lleida Province. Other specimens from the same fossil site and unit are also examined and their former allocation to the same species critically reconsidered, with the conclusion that more than one taxon might be represented in this sample. Previous viewpoints on the systematic placement of E. santonjae, usually considered a discoglossid, are assessed. However, a full revision of the Jurassic and Cretaceous specimens ascribed to the genus is required in order to resolve its phylogenetic position. Hence, E. santonjae is provisionally considered as Anura incertae sedis.

scarcity of other skeletal cemeteries from the time of the early Piasts’ dynasty. Also, findings concerning the site provide a valuable background for the study on the emergence of the early medieval culture of elites. Notably, some of the artefacts unearthed at Sowinki have analogies with Scandinavian finds of the Middle and Late Viking periods.
Sowinki site no. 23A is a multicultural site. The excavations covered an area of about 1.5 ha and revealed altogether 580 features representing 7 chronological-cultural horizons, which include
