Middle Devonian palynomorphs from southern Moravia: an evidence of rapid change from terrestrial deltaic plain to carbonate platform conditions Dispersed fossil miospores and acritarchs have been recovered from the subsurface pelites in the Uhřice-1 borehole, southern Moravia. Spores of ferns, sphenopsids and lycopods with rare marine microplankton (acritarchs and chitinozoans) cysts indicate a predominantly continental environment with a limited marine influence. Dispersed miospores with cysts of unicellular marine microplankton confirm the Middle Devonian, most probably early Givetian (AD lem) age of marine transgression in southern Moravia. Thermal alteration of palynomorphs shows average values, with TAI ranging from 2+ to 3+, corresponding to 60-70 °C.
