node minimum age |
The deposits of the Nsungwe Formation containing Rukwapithecus are constrained by multiple radiometric dates, indicating an absolute age of 24.93 ± 0.49 Ma (Roberts et al., 2010), hence minimally 24.44 Ma.
node maximum age |
The soft maximum constraint is based on members of the stem of Catarrhini, namely the families Propliopithecidae (Propliopithecus, Aegyptopithecus) and Oligopithecidae (Oligopithecus, Catopithecus) that are basal to the cercopithecoid-hominoid split (Rasmussen, 2002; Stevens et al., 2013). These are represented in the Fayûm beds in Egypt, which possess a diverse anthropoid primate fauna, including stem platyrrhines and catarrhines from 33.9 – 28.4 Ma ± 0.1 Myr (Seiffert et al., 2005; Seiffert, 2006). Hence, at the base of the Oligocene at 33.9 Ma ± 0.1 Myr, the Fayûm shows a diversity of primates and other mammals, but no members of crown-group hominoids or cercopithecoids.
|primary fossil used to date this node|
Rukwapithecus fleaglei is based on a right mandible with p4-m3. Phylogenetic analysis by Stevens et al. (2013) places this taxon within crown Catarrhini, basal to the gibbon-great ape split but closer to hominoids than to cercopithecoids. Stevens et al. (2013) also attributed an isolated m3 from the same locality to Cercopithecoidea.
