Micodon 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). Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is M. kiotensis,[2] a very small monkey among the New World species.[3]
Description
Fossils of Micodon were discovered in the
Saimiri. By comparison with Micodon, the hypocone is far smaller in Callimico, where it appears as an excrescence of the lingual cingulum. This cusp is more developed in Saimiri. Overall, the Micodon M1 shows some gross resemblances to certain Saguinus, although none of the specimens examined hardly approach this fossil in hypocone development.[4]
Micodon is clearly within the size range of living
Cebus and Saimiri, as the sister-taxon of the entire group. The upshot of these latter views is that a four-cusped molar would be fully expectable in small, ancestral callitrichine, and even in callitrichin sister-group.[5] The upper first molar (M1) with a subtriangular outline with a narrow lingual side resembles that of the oldest New World primate discovered to date, the Late Eocene Perupithecus from the Peruvian Amazon.[6]
It has been suggested the specimens ascribed to Micodon, smaller than Aotus dindensis,[7] may actually be deciduous teeth of another primate species found at La Venta such as Saimiri annectens or S. fieldsi.[8] More material is needed for a better description of the genus.[9]
A body mass of 400 grams (0.88 lb) has been estimated for Micodon.[10]
Habitat
The Honda Group, and more precisely the "Monkey Beds", are the richest site for
Aotus of Micodon has been placed in the Early Miocene at 17.5 Ma.[15]
