Opis:
Hydrophilic elements, such as sphenopsids and fems, are rare in the flora of the Krasiejów site and they are poorly preserved. One sphenopsid species, Neocalamites merianii, was recognised. It is preserved as impressions, flattened casts, moulds and isolated leaves. So far, only one small fern specimen, determined as Sphenopteris sp., has been found. These elements probably were transported to the site of deposition and did not grow where they were buried.

Opis:
A summary of known crinoid taxa in the Polish part of the Triassic Germanic Basin, including their presence elsewhere, is documented. At present, 13 taxa and 3 ecophenotypes of crinoids have been recorded from that area, only one of them being endemic. In the Lower Muschelkalk and lower part of theMiddleMuschelkalk, taxa widespread both in the Tethys and Germanic Basin, or Tethyan taxa, dominate. In the Upper Muschelkalk crinoids are very rare in Poland, being represented by Encrinus liliiformis and Holocrinus sp. Many of the species occurring in the central part of the Germanic Basin in the Upper Muschelkalk have not been recorded in the eastern part of the basin. The degree of endemism of the crinoid fauna in theMuschelkalk is markedly lower than the degree of endemism of the rest of the benthonic macrofauna. This probably resulted from huge number of crinoids forming "crinoid gardens" that produced large number of larvae, increasing the chances of successful geographical expansion of crinoids.

Opis:
Palaeomagnetic results are presented for 205 samples of cores from the Książ Wielkopolski IG-2, Woźniki K1 and Patoka 1 wells, drilled in the Polish part of Germanic Basin. The magnetic polarity stratigraphy is based on the inclination of the characteristic remanent magnetization, isolated in 60% of the total samples and found to be in general agreement with the expected Late Triassic inclination at the sampling sites. A total of 22 magnetozones from the integration of the three records correspond to about 25% of the published polarity zones for the Upper Triassic sediments that were combined in the worldwide composite polarity-time scale. The magne- tic polarity pattern, defined for the Schilfsanstein, fits very well with the one defined in the Tethys area for the upper part of the Julian sub-stage. According to the magnetostratigraphic data, the uppermost part of the Upper Gypsum Beds (equivalent to the Ozimek Member of the redefined Grabowa Formation) and the lowermost part of the Patoka Member, containing the Krasiejów bone-breccia horizon, can be correlated with the latest Tuvalian (~228.5 Ma) or with the middle part of Lacian (~225 Ma). However, if the “Long-Tuvalian” option for the Late Triassic Time Scale is taken into consideration, the parts of these substages mentioned above should be correlated with ~221.5 Ma and ~218.5 Ma, respectively.

Opis:
A few isolated columnals of a holocrinid have been found in Ladinian Upper Muschelkalk deposits (probably Ceratites Beds) in the OEwioelina valley (northern margin of the Holy Cross Mts.). Although they are poorly preserved and not diagnostic at species level, this is the first occurrence of the genus Holocrinus in the Upper Muschelkalk of the eastern part of the Germanic Basin. This crinoid indicates faunal immigration from the Tethys through reactivated East-Carpathian Gate.

Opis:
The Solvay Quarry of Bernburg is one of the most important ichnosites from the Muschelkalk of the Germanic Basin. Extensive surfaces with long chirotheriid trackways have been discovered and assigned to Chirotherium and Isochirotherium. Some undescribed step cycles from this site are analysed here and assigned to Synaptichnium isp. These footprints belong to a “thick-digit” Synaptichnium morphotype recognised at several Middle Triassic sites of Pangaea that seems to differ from the currently valid Synaptichnium ichnospecies. This is the first occurrence of Synaptichnium from this site and the only including step cycles one from the track-bearing Muschelkalk successions of N Germany and the Netherlands. A comparison between the tetrapod ichnoassociations of marginal marine and alluvial units of the Muschelkalk of the Germanic Basin reveals a similar ichnofaunal composition but different relative proportions between ichnotaxa. Rhynchosauroides and Procolophonichnium occur more often in tidal units, whereas the alluvial units show a higher abundance of chirotheriid tracks and an overall greater track diversity.

Opis:
This paper presents a new sedimentological and palaeogeographic interpretation of the Early to Middle(?) Triassic continental deposits in the Wleń Graben and the Krzeszów Brachysyncline (Sudetes, SW Poland). These two tectonic subunits, located in the peripheral segments of the North Sudetic and Intra-Sudetic synclinoriums, respectively, represent the crucial elements for deciphering the post-Variscan palaeogeographic evolution of the NE termination of the Bohemian Massif. Sedimentological studies and facies analysis show that the Early Triassic siliciclastic deposition in both areas was dominated by fluvial sedimentation of the typical Buntsandstein facies within a gently sloping alluvial plain, locally followed by ephemeral lake environments in the late Early or Middle(?) Triassic. The lithofacies and the measured palaeocurrent directions indicate that the area was drained by braided streams flowing towards the northwest and north. Individual fluvial channels had depths not exceeding 1 m and widths of up to a few metres. Overbank deposits are poorly preserved due to the lateral shifting of channels. Based on available borehole data, an analysis of isopach maps was performed for the first time in the study areas. The study areas are presently separated by crystalline units devoid of sedimentary rocks, but the analysis indicate that they might have been in constant or periodical connection during the Triassic. It is concluded that the present-day extent of Triassic deposits is a result of the primary basin configuration combined with the Middle Triassic to Late Cretaceous erosion and post-Cretaceous tectonic uplift. The paper summarizes the present state of research on the continental Triassic preserved in the terminal parts of the North Sudetic and Intra-Sudetic synclinoriums, presents the first detailed sedimentological logs, and proposes new palaeogeographic interpretation. New findings include bioturbation structures, such as plant-root traces or tunnels formed by invertebrates and possible tetrapod footprints, which shed new light on the sedimentological interpretation of the continental Mesozoic deposits in the NE part of the Bohemian Massif.

Opis:
This study presents the first comprehensive geological analysis of the Triassic Röt sedimentary succession in the Bolesławiec Syncline (BS), North-Sudetic Synclinorium (NSS), SW Poland, and fills information gaps regarding the local lithology, stratigraphy, extent and organisation of this succession. During Triassic time, the BS was located on the southern periphery of the epicontinental Germanic (Central European) Basin. The mixed siliciclastic-carbonate Röt succession transgressively overlies the continental siliciclastics of the Buntsandstein (Bunter), locally with the occurrence of a stratigraphic gap. The Röt succession displays a complex vertical organisation with basic, about 1-m-scale, fine siliciclastic-carbonate couplets, and larger-scale sequences. The well-log profiles allow identification and provisional subdivision of the succession into several 1D sequences, 10–25 m thick, which can be correlated across the study area. The collected palynological material indicated the latest Olenekian to early Anisian age of the local Röt succession. A surprisingly strong thickness diversification of the succession, as well as its frequent incompleteness, evidenced by both palynology and correlation of well-log profiles, is interpreted in terms of local erosion, non-deposition, synsedimentary tectonic activity, and later tectonic deformation. The authors conclude that synsedimentary tectonics resulted in faulting of the area and was the principal factor responsible for differential subsidence and variable sediment accumulation rates. The lower stratigraphic interval of the Röt succession is defined explicitly by the presence of numerous and diversified small-scale soft-sediment deformational structures. The coincidental occurrence of the first marine deposits in the BS area, together with the intense soft-sediment deformation appear to indicate that the end of Early Triassic transgression was associated with intensified regional seismic/tectonic activity. The Röt sedimentary succession of the BS area also was affected by younger tectonic deformation. The pre-Cenomanian events brought about at least local uplift and limited erosion of the Röt succession. Late Cretaceous–Palaeogene inversion was responsible for the final development of the present-day structure of the NSS.
