Primatology Notes #12
EARLY CATARRHINA

  • Earliest Anthropoids— Eocene fossils from Asia:
    • "Eosimiidae" (mostly from China):
      • Eosimias, Phenacopithecus, Bahinia
    • "Amphipithecidae" (mostly from Pondaung formation, Myanmar):
      • Amphipithecus, Pondaungia, Ganlea, Myanmarpithecus;
        Siamopithecus, Bugtipithecus
  • General remarks on Cenozoic African geology & geography
    • Precambrian core;  oil;  volcanics;  rift valleys
  • Fayum deposits of Egypt (Upper Eocene to lower Oligocene):
    • Distinctively African fauna
    • Adapids (mostly Eocene):
      • Plesiopithecus, Anchomomys, Wadilemur, Aframonius, Afradapis
    • Lorisoids(?): Saharagalago
    • Tarsioid: Afrotarsius (Oligocene)
    • Affinities unclear: Nosmips (large premolars)
    • "Parapithecoidea" (mostly Eocene, but several persisted into Oligocene):
      • Apidium
      • Parapithecus
      • Qatrania, Abuqatrania
      • (less known): Biretia, Arsinoea, Serapia, Proteopithecus
      • Possibly ancestral to Oreopithecus (Miocene, Europe)
    • Possible monkey ancestor: Oligopithecus (with incipient C/P3 shear)
    • Possible ape ancestors:
      • Propliopithecus (lightly built, maybe gibbon-like)
      • Moeripithecus
      • Aegyptopithecus (largest and best known; most similar to Dryopithecus)
