REVISIÓN DE ASTEROTHECA GOLONDRINENSIS HERBST, HELECHO PÉRMICO DE PATAGONIA, ARGENTINA
New specimens of Asterotheca golondrinensis Herbst found in the type area (Bajo de La Leona, Santa Cruz province) and in the Tepuel-Genoa Basin (Chubut province), allow a new definition of pinnular characters (margins are shown to be toothed). This type of morphology resembles Nemejcopteris pinnules...

| description | New specimens of Asterotheca golondrinensis Herbst found in the type area (Bajo de La Leona, Santa Cruz province) and in the Tepuel-Genoa Basin (Chubut province), allow a new definition of pinnular characters (margins are shown to be toothed). This type of morphology resembles Nemejcopteris pinnules, but the fructification is more similar to Asterotheca. The Patagonian specimens resemble African (Zimbabwe) material determined as Pecopteris arcuata Halle. The stratigraphic distribution of A. golondrinensis is Early Permian in Chubut and Late Permian in Santa Cruz.
