CANCELLI, Rodrigo Rodrigues; SOUZA, Paulo Alves de and NEVES, Paulo César Pereira das. Fungi, cryptogams and other palynomorphs in the Holocene sediments of the South Coastal Plain of Santa Catarina, Brazil. Acta Bot. Bras. [online]. 2012, vol.26, n.1, pp. 20-37.

This paper presents the results of a palynological analysis carried out on two cores taken from the south Coastal Plain of the Santa Rosa do Sul and São João do Sul municipalities, in the state of Santa Catarina. A basal sample from the Santa Rosa do Sul core furnished a 14C age of 7908±33 yr BP, from the Lower Holocene. Palynological analysis of the material allowed for taxonomic identifications, and resulted in descriptions and illustrations of 54 palynomorphs related to fungi (21), algae (5), acritarchs (1), incertae sedis (1), bryophytes (2), ferns (15), gymnosperm pollen (2) and other palynomorphs (1 bryophyte capsule, 4 invertebrate fragments, and 2 indeterminate palynoforaminifers), which express different ecological patterns. This work aimed to contribute to the knowledge of the plant and fungal fossils remains, and related taxa, recorded from the Coastal Plain of Santa Catarina for the Holocene. Additional palynological analyses will contribute to paleoclimate and paleoenvironmental interpretations of this portion of the Brazilian coast.
