The major ice caps in the late Ordovician lay between base of N. extraordinarius biozone and lower part persculptus biozone, consistent with low values CIA, CIW PIA for Huadi No. 1 well, reflecting a short-lived cold dry climate from top Wufeng-Guanyinqiao Formation to Longmaxi well. These observations provide geochemical record evidence Gondwana glaciation at end South China.

The present publication reports new discoveries of Oligocene and early Miocene aplodontid rodents from the Taatsiin Gol area (Valley of Lakes) in Mongolia. The fossil aplodontids recovered in this area are mainly composed of dental remains, some fragmentary jaws plus one partially preserved skull. Aplodontid rodents have been found from the early Oligocene (local biozone A) to the early middle ...
