Monica Duran, María A. Hunicken, Ana M. Mortan

Abstract


The new species Tschernovia ? velizensis is described. The specimens are compared with illustrations from the palaeofloristic region of Angara (Russia). Close similarities suggest that Tschernovia l was common to Angara and Gondwana. Two additional species are recorded, Phyllotheca sp. cf. P. indica Pant and Kidwai and Giridia sp. cf. G. indica Pant, Natiyal and Lata Misra; these species were described from the Gondwana of India. It is suggested that Bajo de Véliz contained a mixed flora, with elements from both the Angara and Gondwana regions.
