Among others, a relatively rich entomofauna was recently discovered in pyrite-rich black shales, yielding several exceptionally preserved, partly pyritized, body fossils of 'cockroachoid' (Blattodea) insects. Some of these were identified as Anthracoblattina mendesi Pinto & Sedor, which is revised here in a preliminary comparison with all Palaeozoic related species known thus far from South America. Based on these new finds, A. mendesi becomes the most complete Palaeozoic blattoid described so far from South America. Several sub-complete individuals provide additional information about the anatomy of Late Palaeozoic blattoids, in general. The new finds demonstrate that the genus Anthracoblattina is not only a common and typical component of the Euramerican Late Pennsylvanian/early Permian entomofauna, but was also present in the South American Gondwana entomofauna. It is hypothesized that Anthracoblattina immigrated from Euramerica into this part of Gondwana during a climate amelioration event during the course of the Late Paleozoic Ice Age (LPIA), as it is indicated by the transgressive marine Lontras Shale.

Here we present a preliminary description of newly discovered tetrapod burrow systems from the Late

The trackways, preserved as concave epirelief, occur in muddy to fine-grained sandstones intercalated into siltstones, which are interpreted as floodplain deposits. The track imprints are typically arranged in groups of four, two parallel marginal drag marks, positioned symmetrically relatively to midline. A tail-drag mark is occasionally between the track rows and parallel to the midline. Each groups of track impressions consist of three tracks arranged in straight line having an approximately angle of 85-90 degrees with the fourth track impressions, the whole groups constitute an angle between 100 and 110 degrees relatively to trackway midline.

Links to the global marine scale were thus far based on rare and ambiguous isotopic ages only. Here, for the first time, five co-occurrences of spiloblattinid zone species with marine index fossils in North America and the East European Donets basin are used for the construction of a robust biostratigraphical framework for the direct correlation of continental deposits to the Late Pennsylvanian (Kasimovian and Ghzelian) up to the Early Permian (Asselian). This correlation indicates that the base of the Central European regional stage Stephanian is the earliest Kasimovian, the Stephanian B straddles the Late Kasimovian to Early Gzheli...
