The family Dendropithecidae is an extinct family of catarrhine apes. They date from the Early Miocene, around 20-12 million years ago.{{cite book|editor-last1=Begun|editor-first1=D.

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. 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).{{cite journal|display-authors=6|vauthors=Rasmussen DT, Friscia AR, Gutierrez M, Kappelman J, Miller ER, Muteti S, Reynoso D, Rossie JB, Spell TL, Tabor NJ, Gierlowski-Kordesch E, Jacobs BF, Kyongo B, Macharwas M, Muchemi F|date=March 2019|title=Primitive Old World monkey from the earliest Miocene of Kenya and the evolution of cercopithecoid bilophodonty|journal=Proceedings of the National Academy of Sciences of the United States of America|volume=116|issue=13|pages=6051–6056|doi=10.1073/pnas.1815423116|pmc=6442627|pmid=30858323|bibcode=2019PNAS..116.6051R |doi-access=free}} The later Nyanzapithecinae (including Oreopithecus († 7 Ma){{Cite journal|last1=Nengo|first1=Isaiah|last2=Tafforeau|first2=Paul|last3=Gilbert|first3=Christopher C.|last4=Fleagle|first4=John G.|last5=Miller|first5=Ellen R.|last6=Feibel|first6=Craig|last7=Fox|first7=David L.|last8=Feinberg|first8=Josh|last9=Pugh|first9=Kelsey D.|date=2017|title=New infant cranium from the African Miocene sheds light on ape evolution|journal=Nature|language=en|volume=548|issue=7666|pages=169–174|doi=10.1038/nature23456|pmid=28796200|bibcode=2017Natur.548..169N|s2cid=4397839|issn=0028-0836|url=https://discovery.ucl.ac.uk/id/eprint/1570349/1/Spoor_Nengo-et-al_text.pdf}}) appear to be sister to Simiolus.

Description

The taxa included in Dendropithecidae, possess the following traits:{{cite book| vauthors = Harrison T | veditors = Hartwig WC |title=The Primate Fossil Record|date=2002|publisher=Cambridge University Press|pages=311–338|chapter=Late Oligocene to middle Miocene catarrhines from Afro-Arabia|bibcode=2002prfr.book.....H}}

  • 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.
