Opis:
The brown frogs (Rana temporaria-group) are a monophyletic group in the family Ranidae, which have a scarce fossil record in Europe that begins only in the Late Pliocene. A new fossil from the Dietrichsberg locality (Germany, Thuringia) extends their stratigraphic range back to the Early Miocene, and suggests that their origin lies outside the Western Palaearctic, most probably in Asia, with subsequent immigration in the Burdigalian.

Opis:
A new borehole in Rożce (SW Mazovian Lowland) drilled in 2012, combined with a wide variety of research methods (palaeomagnetism, palynological analysis, studies of plant macroremains and textural features of deposits) shed new light on the age and stratigraphic position of the Early Pleistocene deposits, formerly assigned as the Lower Pleistocene. The study focuses on the deposits from 50.7-104.0 m depth, between glacial till of the Nidanian Glaciation (ca. 0.9 Ma) and the Poznań Clays (ca. 5.322 Ma). The deposits situated directly underneath the till (50.7-60.2 m) are related to the Nidanian Glaciation and show a reversed polarity and correlate with the end of the Matuyama Epoch. The deposits from 60.2-104.0 m depth were accumulated during the Early Pliocene, i.e. approximately 5.332-4.6 million years ago. They appear to correlate with the middle part of the Gilbert Palaeomagnetic Epoch and thus they are considerably older than previously thought. The cored section indicates a stratigraphic gap of about 3.5 Ma from the Lower Pliocene to the first advance of the Scandinavian ice sheets into Poland, which are thought to have occurred in the early Middle Pleistocene. The analysed deposits accumulated under variable climatic conditions showing two periods with significant aridity alternated with two periods of increased humidity. Deposits of the arid periods contain no pollen, butaeolian sand quartz grains are found. During periods of more humid climate the area was covered by various types of mixed forest.

Opis:
Normal faults of different orientations appear to be the youngest manifestations of faulting in the Carpathian Foredeep which is filled with Lower to Middle Miocene sediments. Structural studies of the Late Miocene–Pliocene(?) fresh-water molasses of the Witów Series and the overlying Late Pleistocene loessial complex provide a possibility to reconstruct the Late Neogene to Recent (?) stress field in the central part of the Polish Carpathian Foredeep. Strata of such a young age are very rare in the foredeep, thus providing a key record of structural deformation during the latest stages of orogenic evolution of the Carpathian orogen. The molasses are cut by joints, and normal and strike-slip faults, formed in two successive events: (1) a syn-depositional one for the molasses (Late Miocene–Pliocene?), proceeding under NNW–SSE to N–S-oriented horizontal compression, possibly coeval with reactivation of a NE-striking sinistral fault of the Kurdwanów–Zawichost Fault Zone in the basement; (2) a post-depositional one for the molasses (Pliocene to Middle Pleistocene) during N–S to NE–SW-oriented extension, and (3) both syn- and post-depositional ones for the loessial complex (Late Pleistocene). In the first event, reactivation of the NE-striking sinistral fault led to formation of N–S-oriented joints, as well as NW-striking dextral, and NNW-trending normal faults. In the second event, both W–E and NW–SE – oriented joints andWNW-striking normal faults were formed. The latter most probably originated due to reactivation of the Early Palaeocene WNW- and NW-striking normal faults in the basement. In the third event, both NE–SW and NW–SE-oriented joints and NE-striking normal faults formed as a result of reactivation of the SW- and WSW-striking faults in the basement. Therefore, normal faults detected in the Carpathian Foredeep appear to be a result of different successive events. This extensional episode lasted at least to the Late Pleistocene. We also provide evidence for the recent, N- to NNE-directed, tectonic compressive stress, typical for that segment of the Carpathian arc. This stress resulted in the formation of an orthogonal system of joints striking N–S and W–E, produced during
