Title: Givetian palynostratigraphy and palynofacies: new data from the Bodzentyn Syncline (Holy Cross Mountains, central Poland)
Abstract: Givetian samples have yielded well preserved palynomorphs including miospores, prasinophytes, acritarchs, and coenobial algae. Two new miospore species (Grandispora parvula Turnau, sp. nov., and Perotrilites granulaticonatus Turnau, sp. nov.), and two new prasinophyte species (Dictyotidium obesum Turnau, sp. nov., and Polyedrixium skalensis Turnau, sp. nov.) are described. Ten possibly new miospore and prasinophyte forms are described but not specifically named. Two miospore zones of the East European zonal division are distinguished. The direct conodont and goniatite data indicate that the first appearances of (1) Chelinospora concinna, (2) Daillydium pentaster, (3) Samarisporites triangulatus, and (4) Ancyrospora incisa are: upper Lower, or Middle varcus Subzone for (1); Middle varcus Subzone for (2) and (3); and above the base of the hermanni–cristatus Zone for (4). Four successive palynofacies are described: (i) a spore-dominated palynofacies lacking in acritarchs; (ii) palynofacies with acritarchs; (iii) palynofacies with abundant leiospheres; (iv) palynofacies dominated by tasmanitids. The palynofacies changes are possibly related to the eustatic sea-level fluctuations, but the pattern is obviously complicated by changes in surface water circulation and/or fertility.
