However, new discoveries have shown that Chinese pliopi- Accepted 26 May 2020 thecoids were taxonomically diverse and geographically widespread. The earliest pliopithecoids in China Available online 10 July 2020 (and Eurasia) are Dionysopithecus and Platodontopithecus from the Early Miocene of Sihong, Jiangsu (~19À18 Ma). During the Middle Miocene (~15À12 Ma), several species of pliopithecoids are recorded at Keywords: localities in Gansu Province (Laogou), Inner Mongolia (Damiao), Xinjiang Uygur Autonomous Region Pliopithecid (Tieersihabahe), and Ningxia Hui Autonomous Region (Tongxin). Finally, a late-surviving anapithecine Crouzeliid Dental morphology crouzeliid, Laccopithecus robustus, is known from the Late Miocene (~7 Ma) of Shihuiba in Yunnan, which Phylogeny postdates the extinction of pliopithecoids in Europe (during MN 10). Paleontological investigations at a Zoogeography late Early Miocene locality near Fanchang in Anhui Province have yielded a large sample of isolated teeth (more than one hundred) of a previously unknown species of pliopithecoid. The associated micro- mammals indicate an age contemporaneous with the Shanwang Formation in Shandong Province (MN 3 e4, ~18À17 Ma). All of the permanent teeth are represented except for I2. With its unique suite of dental features, the Fanchang pliopithecoid can be attributed to a new species and genus. Shared derived features of the lower molars confirm that the Fanchang pliopithecoid has its closest affinities with Eu- ropean crouzeliids, but a number of primitive traits indicate that it is a stem member of the clade. The evidence points to China as an important center for the early diversification of pliopithecoids. Contrary to previous zoogeographic scenarios, the occurrence of an early crouzeliid in China implies that the Plio- pithecidae and Crouzeliidae may have diverged from a stem pliopithecoid in Asia during the Early Miocene before their arrival in Europe. © 2020 Elsevier Ltd.

The pliopithecoids were a relatively diverse and successful group, with Pliopithecoids are an extinct clade of stem catarrhines from the 10 genera and 19 species currently recognized, spanning more than Miocene of Eurasia. They were the first catarrhines to migrate out of 10 million years, with a geographical range that extended from the Africa, soon after the collision of the Afro-Arabian plate with Iberian Peninsula to eastern China (Andrews et al., 1996; Begun, 2002; Harrison, 2013; Marigo et al., 2014). They became extinct in Eurasia during the Late Miocene, presumably as a consequence of progressive cooling and increased seasonality at higher latitudes * Corresponding author. associated with a corresponding shift from subtropical evergreen E-mail address: [email protected] (Y.
