The family Dendropithecidae is an extinct family of catarrhine monkeys. They date from the Early Miocene, around 20 - 12 million years ago.^[1]

Fossils of the two Dendropithecus species, Dendropithecus macinnesi and Dendropithecus ugandensis, have been found in East Africa, including several partial skeletons of Dendropithecus macinnesi on Rusinga Island in Lake Victoria. Other species are Simiolus andrewsi, Simiolus cheptumoae, Simiolus enjiessi.^[1] Micropithecus clarki and Micropithecus leakeyorum may not be part Dendropithecidae, and may be sister to the crown Catarrhini (or, depending on the definition, the apes and the Cercopithecidae may have emerged in the Dendropithecidae).^[2] The later Nyanzapithecinae (including Oreopithecus († 7 Ma)^[3]) appear to be sister to Simiolus.^[2]

Description

The taxa included in Dendropithecidae, possess the following traits:^[4]

Upper and lower canines strongly bilaterally compressed
P₃ moderately to strongly specialized for sectoriality
Slender limb bones
Humerus with a relatively straight shaft
Medial epicondyle of the humerus is large and medially directed
Epitrochlear fossa is well developed
Zona conoidea is broad and shallow
Trochlear articular surface exhibits minimal spooling
Olecranon fossa is shallow

Micropithecus appears to be sister to the crown catarrhini.^[2]
