Palynology of the Chigua (Devonian) and Malimán (carboniferous) formations in the Volcán Range, San Juan Province, Argentina. Part II. Cavate, pseudosaccate and cingulizonate spores

Palynological analysis of the Chigua and Malimán formations of Middle Devonian and Mississippian age respectively, is presented. They crop out in the Del Volcán Range at the Rio Blanco Basin in western Argentina. In this second part, 40 indigenous species of cavate, pseudosaccate and cingulizonate s...

They crop out in the Del Volcán Range at the Rio Blanco Basin in western Argentina. In this second part, 40 indigenous species of cavate, pseudosaccate and cingulizonate spores from both units are illustrated. The species Geminospora sp. cf. G. tuberculata var. tuberculata McGregor is recorded in the Middle Devonian of South America for the first time. The following species are also recorded in the Mississippian of South America for the first time as Crassispora invicta Playford, Densosporites asperus Braman and Hills, Densosporites gracilis Smith and Butterworth, Densosporites secundus Playford and Satterthwait, Densosporites sp. cf. D. triangularis Kosanke, Gorgonispora sp. cf. G. crassa (Winslow) Higgs et al., Lophozonotriletes dentatus Hughes and Playford, Spelaeotriletes echinatus (Hacquebard) Utting, Velamisporites perinatus (Hughes and Playford) Playford. Some possibly reworked species (scolecodonts, paleomicroplankton and spores) from the Malimán Formation are illustrated and some of them are also described. © Asociación Paleontológica Argentina.
