Abstract (in english)
   Enigmatic, so far undescribed organic-walled microfossils incertae sedis are reported from the Arenigian/Llanvirnian of the Argentine Precordillera and compared with similar specimens from Bohemia. The fossils show a spherical to subspherical central body with an "opening" and a cell-like wall structure. The two occurrences belong to different palaeogeographic provinces. The Precordillera is considered to be an attached terrane with faunistic affinities to the Laurentian warm-water area whereas the Prague Basin is part of the cold-water peri-Gondwana realm. The possible biological affinities of the microfossils are discussed
