| dc.description | Se describen e ilustran diez especies de Pteridophyta procedentes de estratos de la parte media de la Formacion La Ternera (Triasico Superior), aflorantes en la quebrada La Cachivarita, afluente norte de la quebrada Paipote, Provincia de Copiapo, III Region, Chile. Se trata de Rienitsia ternerae, Todites chilensis, Todites sp., Neocalamites carrerei, Asterotheca rigbyana, Asterotheca fuchsi, Cladophlebis mendozaensis, Cladophlebis kurtzi, Gleichenites cachivaritensis y Dictyophyllum (D.) tenuifolium, de las cuales las dos primeras son nuevas. El conjunto paleofloristico confirma la edad triasica superior asignada con anterioridad a la Formacion La Ternera. El estudio sedimentologico de la seccion que incluye tales estratos permitio distinguir cinco facies diferentes que, en conjunto, son interpretadas como depositos en un lago que progresivamente se torna mas somero. | es-ES |
| dc.description | Ten species of Pteridophyta from the middle part of the La Ternera Formation (Upper Triassic), in quebrada La Cachivarita, Copiapó Province, northern Chile, are described and figured. They include Rienitsia chilensis, Todites chilensis, Todites sp., Neocalamites carrerei, Asterotheca rigbyana, Asterotheca fuchsi, Cladophlebis mendozaensis, Cladophlebis kurtzi, Gleichenites cachivaritensis and Dictyophyllum (D.) tenuifolium, being the first two, new ones. This assemblage agrees with an Upper Triassic age for the La Ternera Formation as formerly proposed. A sedimentological analysis of the section which includes the fossiliferous strata, recognizes five different facies which are interpreted as deposits in a lake becoming progressively shallower. | en-US |
