Miocallicebus
Miocallicebus 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 mya).The specimen consists of a right maxillary fragment preserving a root of M1, a complete M2, and a badly damaged M3,[3] discovered at the Bolivia Site in the Tatacoa Desert of Huila, south-central Colombia.[4] The fossil remains were uncovered just above the Tatacoa Sandstone Beds of the La Victoria Formation, which has been dated to the Laventan with a range from 13.86 to 12.38 mya.[2] The estimated weight for Miocallicebus, considered similar to but much larger than the extant genus Callicebus,[5][6] is 1,500 grams (3.3 lb).[10] 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.
