In the Lusitanian Basin (west-central Portugal), Upper Jurassic (Oxfordian) sediments were investigated in order to identify paleontological assemblages of charophytes. Systematic studies were undertaken on specimens obtained from four field sections (Pedrogao, Vale de Ventos, Memoria and Valverde). These studies revealed the presence of new forms of Porocharaceae (Porochara pedunculatan. sp) and of forms previously unknown in this region (Auerbachichara cf. saidakovskyi), as well as P. raskyae, P. minima, P. fusca, P. sulcata, P. kimmeridgensis, Aclistochara longiformis and Porochara sp. Comparison of the charophyte paleofloras recognized in all of the studied sections has allowed the definition of three different assemblages which, coupled with other data, help to correlate these successions of Early (?) to Middle (Late?) Oxfordian age.
