Data from: A parapithecid stem anthropoid of African origin in the Paleogene of South America

Phylogenetic evidence suggests that platyrrhine (or New World) monkeys and
caviomorph rodents of the Western Hemisphere derive from source groups
from the Eocene of Afro-Arabia, a landmass that was ~1500 to 2000
kilometers east of South America during the late Paleogene. Here, we
report evidence for a third mammalian lineage of African origin in the
Paleogene of South America—a newly discovered genus and species of
parapithecid anthropoid primate from Santa Rosa in Amazonian Perú.
Bayesian clock–based phylogenetic analysis nests this genus
(Ucayalipithecus) deep within the otherwise Afro-Arabian clade
Parapithecoidea, and indicates that transatlantic rafting of the lineage
leading to Ucayalipithecus likely took place between ~35 and ~32 million
years ago, a dispersal window that includes the major worldwide drop in
sea level that occurred near the Eocene-Oligocene boundary.
