node minimum age 11.6 Ma The Chinji Formation of Pakistan corresponds to magnetic polarity chron 5Ar, estimated to be ca. 12 Ma before present (Kappelman et al., 1991). This correlates to the Serravallian stage, the top of which is at 11.6 Ma, our minimum estimate for the divergence of the orangutan from other great apes. | ||
|
node maximum age 33.9 Ma As a soft maximum we suggest the first diverse occurrence of anthropoids from the earliest Oligocene of the Fayûm, Egypt. These primates comprise a diverse radiation just on the Oligocene side of the Eocene-Oligocene boundary at 33.9 Ma (Seiffert, 2006; Gradstein et al., 2012), and lack derived features of the extant great ape lineages. | ||

phylogenetic justification
Sivapithecus is identified by phylogenetic analysis as a member of total-group Ponginae, a stem gibbon, and so nested within crown Hominidae (Ward and Kimbel, 1983; Seiffert, 2006). |
