摘要:The Chafing Basin situated in southeast of Hunan. The "Red Beds" of late Mesozoic and early Tertiary extensively developed in the basin and attain great thickness of 3279 meters. There was no determinable fossil found from these beds until 1964.
    In winter of 1972, a field party of IVPP was rented to the basin and collected some vertebrate fossils from the "Red Beds".
    As the result of the Party`s work, the "Red Beds" of Chaling Basin may be divided into two formations:
    1.  Daijiaping Formation: Late Cretaceous in age, occupied almost in the whole basin, overlying unconformably on Jurassic or even older system. Thickness about 911-3226 m.
    2.  Zhaoshi Formation: Middle Palaeocene, distributed on the south of Chaling City, overlying disconformably on the Daijiaping Formation. Some mammalian fossils including Pantodonta, Condylarthra, Anagalida, and Tillodontia etc. were collected in this formation.  Thickness about 53 m.
