This paper is the first report of wild male Sichuan snub-nosed monkeys (Rhinopithecus roxellana) engaging in homosexual mounting within an all-male juvenile unit in the Qinling Mountains of China.

The taxonomy and biostratigraphy of the Talicypridea-Cypridea-Nanxiongium ostracod fauna from the Nanxiong Group in the Nanxiong Basin is of great importance for the subdivision and correlation of the Upper Cretaceous non-marine strata in China.

suzulii and Arctica subexten-sa and the gastropod Biplica obliqu discovered in the Dawaxung Group have the features of the Creta-ceous fauna,which suggests that the Dawax ung Group was deposited in the Early Cretaceous Hauterivian-Albrian rather than in the Mid-Upper Jurassic and corresponds completely with the upper part of the Ze-long Group in the area.
