Abstract (in english)
   Recovery of palynomorphs from two boreholes drilled in the Pando Department, northern Bolivia, demonstrates a succession of assemblages of terrestrial and marine organic-walled microfossils of the latest Silurian/earliest Devonian to Carboniferous age. The Tequeye, Tomachi and Toregua Formations were sampled and analysed for palynology, 60 samples were processed, most of them beimg quite productive. 230 taxa of palynomorphs have been determined so far, including 47 genera of dispersed miospores, rare megaspores and 44 genera of acritarchs. Several selectes samples from Pando X-1 borehole yielded diversified Early Devonian chitinizoan asseblages. The age of diamictites of presumed glacial origin has been correlated with the LL-LE palynozones. Thereby, further evidence of the Late Fammenian glacial episode reported in the Solimoes and central Parnaíba Basins is confirmed
