"Palynological data from the Bayocian Cura Niyeu Fm. of Sierra de Chacai Co, Neuqudn Basin, Argentina". - In marine strata with Sonninia ssp. and Otoites spp., 5 microfloristic assemblages have been identified. More than 60 terrestrial and 8 marine species of palynomorphs belong to the following genera: Alisporites, Anapiculatispohtes, Antulsporites, Araucariacites, Baculatisporites, Biretisporites, Callialasporites, Cerebropollenites, Classopollis, Concavisporites, Converrucosisporites, Cycadopites, Deltoidospora, Dictyophyllidites, Duplexisporites, Equisetosporites, Gleicheniidites, Inapertisporites, Interulobites, Ischyosporites, Leptolepidites, Lycopodiumsporites, Marattisporites, Microcachryidites, Monosulcties, Nevesisporites, Perinopollenites, Peromonolites, Phrixipollenites, Podocarpidites, Staplinisporites, Stereisporites, Taurocusporites, Todisporites, Trisaccites, Uvaesporites, Verrucosisporites, Vitreisporites, Baltisphaeridium, Campenia, Cymatiosphaera, Leiosphaeridia, Lancettopsis, Micrhystridium, Pleurozonaria, Veryhachium. The microflora is compared with other palynomorph assemblages from the Middle and Upper Jurassic of the Neuquen Basin and other regions
