Patasola magdalenae
Patasola is an extinct genus of New World monkeys from the Middle Miocene (Laventan in the South American land mammal ages; 13.8 to 11.8 Ma).[2] Fossils of Patasola, a small insectivorous/frugivorous primate,[3] were discovered in both the La Victoria and Villavieja Formations above and below the "Monkey Beds" of the Honda Group, that has been dated to the Laventan, about 13.4 to 11.8 Ma.[6] The estimated weight of Patasola was 480 grams (1.06 lb),[7] similar in size to the extant genus Leontopithecus.[10] The Honda Group, and more precisely the "Monkey Beds", are the richest site for fossil primates in South America.[11] It has been argued that the monkeys of the Honda Group were living in habitat that was in contact with the Amazon and Orinoco Basins, and that La Venta itself was probably seasonally dry forest.
