Where: Jiangsu, China (32.1° N, 118.7° E: paleocoordinates 32.9° N, 116.4° E)
• coordinate based on nearby landmark
When: Shanwang Formation, Burdigalian (20.4 - 16.0 Ma)
• He et al. 2011: Samples SW2007 and SW01 from the basalt just below the fossil-bearing diatomaceous sediments of the Shanwang Formation yield near plateau age of 17–18 Ma. Sample SW8-13 from a lava flow in the Yaoshan Formation yields an age of 17.3 ± 1.4 Ma (Fig. 6b). These age determinations suggest that, the age of the Shanwang biota is ca. 17 Ma, which is late Burdigalian Age of the Early Miocene in the widely-used Geologic Time Scale 2004 (Gradstein et al., 2004). The age of 17 Ma presented in this study of the Shanwang biota supports previous interpretations that this mammal fauna can be correlated with MN4 in the middle Orleanian of the European Land Mammal Age (Steininger et al., 1996; Steininger, 1999; Agustí et al., 2001), the late Hemingfordian of the North American Land Mammal Age (Woodburne and Swisher, 1995; Alroy, 2000), and the Santacrucian of the South American Land Mammal Ages (Flynn and Swisher, 1995).
