The sec tion con sists of con ti nen tal and coastal de pos its con tain ing fos sil as sem blages span ning nearly 25 My of changes in ter res trial plants and some groups of in ver te brates and tetra pods. Based on macrofossils and pol len and spores, the broader char ac ter is tics of the flora in this suc ces sion are pre sented. The flo ral as sem blages show typ i cal Early Ju ras sic char ac ter is tics and con tain lycopsids, sphenopsids, ferns, cycadaleans, bennettitaleans, gnetaleans and ginkgoaleans, as well as co ni fers, and are sim i lar to other Hettangian-Toarcian flo ral suc ces sions in Eu rope, show ing the pres ence of a vast co nif er ous for est dom inated by Hirmeriella in the early Hettangian, re placed by ginkgophyte-dom i nated flo ras in youn ger stages and araucarian coni fer-dom i nated for ests in the late Pliensbachian. Di no saurs are doc u mented mainly from their trace fos sils (tracks and cop ro lites). Six dis tinct track as sem blages (stratigraphically sep a rated ichnoassemblages) of dif fer ent ages can be iden tified.

Geo log i cal Quar terly, 59 (4): 615-653, doi: 10.7306/gq.1239 Based on quan ti ta tive and qual i ta tive anal y ses of Tri as sic miospore as sem blages from dif fer ent re gions of Po land, cli ma tic changes have been doc u mented. The ma te rial came from pub lished and ar chi val works of Or³owska-Zwoliñska and of the pres ent au thor. It com prises ten palynological zones dis tin guished in the Tri as sic of Po land. Two dif fer ent palynological meth ods were ap plied in this study -palyno-palaeoclimatic (PPC) model and sporomorph ecogroup (SEG) model -to ob tain palaeoclimatic and palaeoenvironmetal data.The PPC model is based on the per cent ra tio of xe ro phyt ic and hygrophytic el ements in miospore as sem blages. Dom i nance of xe ro phyt ic el e ments (spores and pol len grains of xe ro phyt ic plants) in dicates dry cli mate con di tions, and a higher ra tio of hygrophytic forms (spores and pol len grains of hygrohytic plants) re flects hu mid phases. A sig nif i cant dom i nance of xe ro phyt ic el e ments in ma jor ity of the ana lysed as sem blages sug gests a dry climate dur ing most of the Tri as sic. An in crease of the num ber of hygrophytic el e ments is ob served in the as sem blages found in the Mid dle Buntsandstein, Up per Muschelkalk, Lower Keuper (Sulechów Beds), Schilfsandstein, Jarkowo Beds and Wielichowo Beds. It marks cli mate humidification in the Olenekian, Ladinian, Mid dle Carnian, Late Norian and Rhaetian, respec tively. The SEG model, con nect ing dis persed spores and pol len with the floristic palaeocommunites that oc cu pied deter mined eco log i cal niches, was ap plied for palaeoenvironmetal in ter pre ta tion. Four SEGs were re cog nized in the Tri as sic spore-pol len as sem blages: Up land, Low land and River, Coastal, and not at trib uted. The Uppland SEG dom i nates in these as sem blages with ex cep tion of the spec tra found in the Lower and Mid dle Buntsandstein, Up per Muschelkalk, Lower Keuper, Schilfsandstein, Jarkowo Beds and Wielichowo Beds, where the Low land and River SEG oc cur more nu mer ously.

Not all deformational structures are tectonic in nature. Those that do not form under the influence of endogenic causes, but are the result of, for example, gravity, compaction or diapiric extrusion, are referred to as non‐tectonic phenomena. An example of such deformation is the steep and overturned dips of Callovian and Oxfordian layers in the gently folded Mesozoic cover of the Holy Cross Mountains. Their steepening was a result of processes taking place in the underlying ductile formations of Keuper–Rhaetian (Upper Triassic) and Bathonian, slightly enhanced by glaciotectonics. The latter are dominated by claystones, with a minor share of mudstones and sandstones. Their plasticity was due to a significant share of mixed‐layer minerals of smectite‐illite type, which under conditions of high water could swell. Low‐density water‐saturated clays were extruded from under the edge of a limestone slab leading to its deformation. The diapiric flow of the clay‐mass was stimulated by low temperature, high water saturation of rocks and mechanical disintegration associated with freeze–thaw processes during the Pleistocene.
