MICROFITOPLANCTON ORGÁNICO DE LA SECCIÓN INFERIOR DE LA FORMACIÓN SANTA MÁXIMA, CARBONÍFERO SUPERIOR, ARGENTINA.

Eduardo G. Ottone, Graciela B. García

Abstract


Organic-walled microfossils are described from the lower section of the Santa Máxima Formation, Upper Carboniferous, Argentina. Two taxa are identified: Leiosphaeridia sp. and Veryhachium trispinosum (Eisenack 1938) Deunff 1954. Originally placed in Sylvanidium Loeblich 1969 and Villosacapsula Loeblich and Tappan 1976 on the basis ofbearing an apparent spinose vesicle wall now proved to be psilate, the veryhachid specimens of the unit are formally transferred to Yeryahachium trispinosum. Comparisons with other marine, mainly Gondwanian, palynofloras of similar age, are discussed.
