The palynology of the Ordóñez Formation (Pennsylvanian) in the Chacoparaná Basin, northern Argentina
A detailed palynological analysis of the Chacoparaná Basin is presented. Thirty-one samples were recovered from boreholes YCF.CO1, YCF.CO2 and YCF.CO3, corresponding to the lower part of the Ordóñez Formation, at the Santiago Temple locality (Córdoba Province, Argentina).

| description | A detailed palynological analysis of the Chacoparaná Basin is presented. Thirty-one samples were recovered from boreholes YCF.CO1, YCF.CO2 and YCF.CO3, corresponding to the lower part of the Ordóñez Formation, at the Santiago Temple locality (Córdoba Province, Argentina). Three new species are described: Calamospora fissurata sp. nov., Retusotriletes archangelskyi sp. nov. and Horriditriletes chacoparanensis sp. nov.; Leiotriletes malanzanensis nov. nom., Endosporites menendezi nov. nom., emend. are proposed to replace L. tenuis Azcuy and E. parvus Menéndez; and the following species are proposed as new combinations: Brevitriletes coalescens
(Menéndez & Azcuy) nov. comb., Brevitriletes papillatus (Menéndez & Azcuy) nov. comb., B. sparsus (Menéndez & Azcuy) nov. comb., B. delicatus (Menéndez) nov. comb. and Indotriradites malanzanensis (Azcuy) nov. comb. Two different associations were identified and are compared with the known biozones from the same basin and other biostratigraphical schemes for basins from central western Argentina. The palynological assemblage can be referred, in part, to the Potonieisporites–Lundbladispora Biozone (Chacoparaná Basin) and the Raistrickia densa–Convolutispora muriornata Biozone (central western basins of Argentina, latest Serpukhovian–Bashkirian). |
