Hi! French naturalist & ethnobiologist, I discovered this fossil fern in the 1990's when surveying the puna investigating Maca (Lepidium meyenii Walpers) and collecting actual Lepidium sp. (Brassicaceae) at the altitude of 4250 m, some km eastwards of Lake Junin, in the High Andes of Peru. The specimen was broken into two pieces, on the ground of the puna, some meters from each other. Lenght: 11 cm. Wide: 7 cm. As I am not paleobiologist unfortunately, please would you help me to identify it ? Carboniferous/Early Carboniferous ? Adiantites (lindseaeformis?) ? Esphenopteris ? I have found other fossils (there are a lot in this calcareous region, you can see on the 2nd picture ) and I shall post them next time. Many thanks in advance. All the best.

Hi! In the same (calcareous) region of Lake Junin (or Lake Chinchaycocha, in quechua), in the High Central Andes of Peru, where I was investigating Maca (Lepidium meyenii Walpers) I found in tne 1990's this nice coral fossil specimen at the altitude of 4200/4300m. Measure below in cm. What do you think about it ? Thank you in advance ! Warmfully Pierre-Olivier Combelles Institut Andin d'Etudes Ehnobiologiques (France)
During the same years (1997-2000) and in the same region of the High Andes of Peru, I discovered the fossil fern and the fossil coral presented in my two other topics: http://www.thefossilforum.com/index.php?/topic/72054-fossil-fern-in-the-high-andes-of-peru/#comment-758432 http://www.thefossilforum.com/index.php?/topic/72061-coral-fossil-of-the-high-andes-of-peru/#comment-758464 , I took this picture (slide poorly scanned, sorry) of ammonites in the stone wall of San Pedro de Parish, an old little abandonned church of the beginning of the Hispanic Colony, on the shore of Lake Junin (or Chinchaycocha, en quechua), altitude 4125m. What do you think about it, especially in relation with the branching coral ? Thanks
