New Pliopithecoids from the Miocene of Asia
Catarrhine primates originated in Afro-Arabia during the Eocene and were restricted to this zoogeographic province until the early Miocene. The pliopithecoids, a group of primitive catarrhines, were the first to appear in Eurasia at about 20-18 million years ago. Dionysopithecid pliopithecoids from the early Miocene (18-17 million years ago) locality of Sihong in China are the earliest known Eurasian catarrhines. During the middle and late Miocene pliopithecoids diversified, and were represented by more than a dozen species distributed across Eurasia from Spain to China. During the late Miocene, global cooling led to major ecological changes, and pliopithecoids became extinct in Europe about 9 million years ago. However, they lingered on in the subtropical woodlands and forests of southern China until at least 7 million years ago. Terry Harrison’s recent work in this area has focused on the taxonomy, phylogenetic relationships, and biogeography of the pliopithecoids from Asia. Some exciting new discoveries from China and India show that Asian pliopithecoids were much more diverse than previously known.
