Fija³kowska-Mader, A., 2015. A re cord of cli ma tic changes in the Tri as sic palynological spec tra from Po land. 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.
