Cebupithecia 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 million years ago). Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is C. sarmientoi.[1][2]

Description

Fossils of Cebupithecia were discovered in the "Monkey Beds" of the

aotins than pitheciines, but its overall pattern is unlike any living platyrrhine group or any of the known fossils.[5]

Movement

Cebupithecia also exhibits a relatively large medial protuberance, which is smoothed, another resemblance to aotins. The significance of these characteristics is difficult to interpret. Cebupithecia may be the most primitive known pitheciine, retaining shared primitive resemblances with aotins and cebines. Alternatively, its unusual morphology could reflect a unique, derived (for pitheciines) locomotor pattern. The talar features that distinguish Cebupithecia from other pitheciines indicate that leaping was relatively more frequent, as is also indicated by other postcranial features. The locomotor behavior of Cebupithecia has been reconstructed as frequent

Pithecia, to which the genus is related.[2][6]

Later research suggests that Cebupithecia may have employed its tail differently from most nonprehensile-tailed platyrrhines living today, behaviors that possibly involved tail-bracing or twisting during hindlimb (pedal grasping) suspensory behaviors. Such behaviors may serve as a preadaptive model for the full-fledged evolution of below-branch tail suspension and prehensility seen in other New World primates.[7]

Evolution

The evolutionary split between Pitheciidae, of which Cebupithecia, and Callicebus, including Miocallicebus, also found in the Honda Group, has been placed at 15.2 million years ago.[8]

The Honda Group, and more precisely the "Monkey Beds", are the richest site for

Stirtonia tatacoensis have also been uncovered.[11][12][13]
