Abstract

Systematic descriptions of 30 palynomorphs from the Miocene Chiquirnil Forrnation, at Río Vallecito Locality, are presented. This unit yield a terrestrial palynological association cornposed of Pinophyta and Magnoliophyta species. The rnost abundant Pinophyta are: Podocarpidites martoickii Couper, P. exiguus Harris, P. rugulosus Romero, P. elegans Romero, P. microreticutoidata Cookson and Equisetosporites noiensis (Cookson) Romero; and the Magnoliophyta species are: Granniditcs media (Cookson) Potonié, Craminidites sp., Cyperaceapollenites neogenicus Krutzsch and Tricolpites sp. Among thern Sparganiaceaepollenites delicata sp. nov. is probably related to Typhaceae and/or Sparganiaceae. This association suggests for the Upper Miocene Chiquimil Formation the existence of a marshy environment with xerophytic savannah and mountain forest vegetation.
