Zygospores of Zygnemataceae (Chlorophyta) from the middle tertiary of Tierra del Fuego, Argentina

This paper deals with the description of seven types of fossil zygospores referable to the family Zygnemataceae (Chlorophyta) recovered from the Cullen Formation (middle Tertiary) in the northeast of Tierra del Fuego. These are: Mougeotia sp. cf. M. laetivirens, Mougeotia sp., Spirogyra sp. Tipo A,...
