194 E. W. Berry — Carboniferous Plants from Peru, 



Dept. of Cuzco. Steinmann (Geol. Rundschau, Bd. 2, pp. 

 50-51, 1910) records Lepidodendron and Rhacopteris 

 inaequilatera Goppert from near Huichaycota on the Rio 

 Huallaga in the Eastern Range 1 km. south of Huanuco in 

 the Department of that name. . In the same publication 

 similar deposits, said to contain Archaeo catamites radia- 

 tus and Lepidodendron cf. Volhmanni are recorded from 

 Retamito, which is between San Juan and Mendoaz in the 

 Argentine Cordillera. 



I think that there can be no doubt that the Paracas 

 Carboniferous is younger than the Dinantian stage of 

 the European section and that it corresponds to the West- 

 phalian stage. The marine Carboniferous of the Andes 

 is usually considered to be of Uralian age, that is to say, 

 Stephanian in terms of the continental section. Whether 

 or not the marine series represents more than Uralian has 

 not yet been definitely determined. The finding of one at 

 least of the Paracas plants in the lower part of the section 

 on the Copacabanya peninsula, Bolivia, several hundred 

 feet below the fossiliferous limestones, would lead to the 

 inference that the Paracas plant-bearing Carboniferous 

 is older than the bulk of the marine Andean Carbonifer- 

 ous and especially the highly fossiliferous portion of the 

 latter.
