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...

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.
