The East China Sea area (including most of the Okinawa Trough) may have been subaerial between 1.6-1.3 Ma, thus indicateing that the Ryukyu Arc region may have been part of the Eurasian continent at that time. During two major development periods (sometime between 1.6 - 1.0 Ma, and 0.2 - 0.025 Ma) the Ryukyu Arc may have been nearly connected to the Chinese continent through Taiwan as a land bridge (Kimura, 2000), as reflected by a similar fauna composition and other characteristics of South China.
