Early-Late Permian palynostratigraphy and palaeobiogeography of Vestfjella, Dronning Maud Land, Antarctica
The preliminary results of a palynological investigation of 62 samples from the southern section of a sedimentary sequence exposed at Fossilryggen in the Vestfjella mountain range in Dronning Maud Land, Antarctica are reported. The sequence, which is cut by dolerite dykes, is considered to have been...

The preliminary results of a palynological investigation of 62 samples from the southern section of a sedimentary sequence exposed at Fossilryggen in the Vestfjella mountain range in Dronning Maud Land, Antarctica are reported. The sequence, which is cut by dolerite dykes, is considered to have been deposited in a near-shore marine environment. Palynomorphs recovered show high degrees of thermal alteration and various states of preservation; 55 palynomorph taxa have been identified, including the stratigraphically important Didecitriletes ericianus, Microbaculispora villosa, M. trisina, Horriditriletes filiformis, Praecolpatites sinuosus, Weylandites lucifer, Protohaploxypinus rugatus, Striatopodocarpidites cancellatus and S. fusus.
