“…For the first time in the Skole Unit, the planktonic foraminiferal assemblage allow the recognition of recently proposed latest Cretaceous biozones. Moreover, the microfauna of the Skole Unit contributes to our understanding of migration "gates" between the Boreal and Tethyan biogeoprovinces (Gasiński 1997(Gasiński , 1998Marcinowski & Gasiński 2002). The marginal part of the Skole Unit of the Polish Carpathians was located near the Boreal-Transitional domain (Kollmann & Zapfe 1992) in proximity to the so-called Lviv Gate (Marcinowski & Gasiński 2002).…”

Abstract:The Ropianka Formation (also known as the Inoceramian Beds) in the marginal part of the Skole Nappe (Husów region, the Gaj section) contains abundant, diverse and well preserved assemblages of Maastrichtian planktonic and benthic foraminiferids, assigned to the middle-upper part of the Gansserina gansseri Zone and to the Abathomphalus mayaroensis Zone. The composition of the assemblages indicates fluctuations of organic matter flux to the marginal part of the Skole Basin floor in the studied interval. The studied taxa are typical of the "transitional zone" between the Tethyan and the Boreal domains. The disappearance of planktonic foraminifers in the uppermost part of the section and appearance of some agglutinated taxa (Rzehakina fissistomata; abundant Conglophragmium irregularis and Glomospira charoides) points to a Paleocene age.

“…Their ex tinc tion was caused by the for ma tion of the OMZ in the sur face wa ters dur ing the Late Albian (OAE1d) and the lat est Cenomanian (OAE2). Some of these, as eurytopic forms, had a wider eco log i cal tol erance (Heterohelix, Hedbergella, Guembelitria), and other ones, as stenotopic forms, were very en vi ron men tally sen si tive (Rotalipora, Praeglobotruncana; Leckie, 1987;Gasiński, 1997;Hart, 1999;BouDagher-Fadel, 2013). The first were shallowdwelling forms, while the lat ter rep re sented deep dwell ing micro fossils.…”

Geo log i cal Quar terly, 59 (1): 215-228, doi: 10.7306/gq.1206 Foraminifera and cal car e ous nannoplankton, as well as other fos sils from the Albian-Turonian de pos its of the West ern Polish Carpathians, are dis cussed in re la tion to changes in depositional en vi ron ments, which were con trolled by geotectonic activ ity, sea level changes, and anoxic and bi otic events. The dis tri bu tion and di ver sity of fos sils in the de pos its stud ied have been re lated to global sea level fluc tu a tions or lo cal sea level rise and fall. Dur ing the Albian to the Early Cenomanian, and in the Turonian, the lo cal sea level falls led to an in creased sup ply of coarse-grained ma te rial rich in si li ceous and some times cal car e ous fos sils and rock ma te rial. This cy clic pro cess has con trib uted to changes in the ma rine biota. In the Albian, monospecific foraminiferal as sem blages with a surficial infauna which col o nized bot tom wa ters af ter pe ri ods of or ganic in flux and ox y gen de fi ciency (OAE1b), evolved into more vari able as so ci a tions in clud ing deep infauna which in di cate more aer o bic con di tions. Un der these con di tions plank tonic and cal car e ous ben thic fos sils (tintinnids, cal car e ous nannoplankton, and foraminifera) were also pre served. Their pres ence was as so ci ated with the sup ply of terrigenous ma te rial from shal low-wa ter en vi ron ments and land, which were eroded dur ing re gres sions con trolled by lo cal tec tonic ac tiv ity.
