Opis:
Disarticulated crinoid columnals and pluricolumnals from the Famennian of the Holy Cross area were analysed. Sixteen crinoid taxa were distinguished, only one of which is based on stems attributed to a calyx−based genus, and the others are classified within artificial supraspecific units. Two of these are new: Schyschcatocrinus levis sp. nov. and Cosmocrinus polonicussp. nov. The described crinoid fauna shows distinct extinction−recovery temporal pattern: the Frasnian–Famennian crisis affected 50% of stem−based families and 70% of late Frasnian stem−based genera. The succession of crinoid faunas represented by three faunal intervals has been identified and correlated to standard conodont zones: FIa, Palmatolepis triangularis Zone (relic “Frasnian” crinoid assemblage Schyschcatocrinus delicatus–Calleocrinus kielcensis), FIb, Pa. crepida to Pa. marginifera zones (crinoid assemblage Calleocrinus kielcensis–Schyschcatocrinus levis) and FIc, Pa. trachytera to S. praesulcata zones (crinoid assemblage Cosmocrinus polonicus–Acbastaucrinus affectatus). The succession was controlled mostly by eustatic factors.

Opis:
Early–Middle Frasnian ostracods and crinoids from Wietrznia in the Northern Kielce subregion of the Holy Cross area were analyzed. Twenty three ostracod species assigned to thirteen named genera, as well as eighteen crinoid species including the representatives of fifteen stem−based taxa were distinguished. For most of the species open nomenclature is applied. The composition of ostracod assemblage changes from moderately diverse in the lower part of the Palmatolepis transitans Zone to poorly diverse in its higher part. Lack of ostracods in the uppermost part of the Pa. transitans Zone and in the Palmatolepis punctata Zone is noted. The crinoid distribution pattern comprises the interval of relatively high diversity, interrupted in the uppermost part of the Pa. transitans Zone, and the interval of temporary recovery in the lower Pa. punctata Zone. Such distribution patterns point to deterioration of environmental conditions across the Early–Middle Frasnian transition, coinciding with a large−scale C−isotopic perturbation superimposed on intermittent, two−step eustatic sea level rise. On the other hand, impoverished, surviving crinoid faunas and absence of ostracods in the Pa. punctata Zone indicate the overall long−term deterioration of life conditions through the major C−isotope anomaly time span. However, this may also result from synsedimentary tectonic pulses, causing block movements and large−scale resedimentation phenomena on the northern slope of the Dyminy Reef during the basal Middle Frasnian sea level rise.
