Zong Guanfu (Institute of Vertebrate Paleontology and Paleonthropology, Academica Sinica, Beijing, 100044)
According to the section near the Gantang village, Jiang et al. established the "Gantang Formation" and considered the Xiaohean beds bearing the ramapithecoid mammalian fauna to be "Gantang Formation". But they are different geological bodies and contain different mammalian fossils respectively and there is no contraposed continuity between them. Jiang et al. regarded the "Gantang Formation" as not corresponding to the Shagou Formation but overlapping the Shagou beds. The Shagou and Gantang sections were deposited in the similar depositional environment and contain similar mammalian fossils so that the "Gantang Formation" is just the Shaogou Formation and invalid.
