Astragalar morphology of late Eocene anthropoids from the Fayum Depression (Egypt) and the origin of catarrhine primates
ER Seiffert, EL Simons - Journal of human evolution, 2001 - Elsevier
The phylogenetic relationships of the late Eocene anthropoids Catopithecus browni
andProteopithecus sylviae are currently a matter of debate, with opinion divided as to
whether these taxa are stem or crown anthropoids. The phylogenetic position of
Catopithecus is of particular interest, for, unlike the highly generalized genusProteopithecus,
this taxon shares apomorphic dental and postcranial features with more derived undoubted
catarrhines that appear in the same region 1–2Ma later. If these apomorphies are …
