In February 1999, we visited several fossil yielding areas in northern Thailand. These areas, except for the Hab Pu Dai Cave Deposit locality, are of Miocene age (Ducrocq et al. 1994, Saegusa et al. 1999). A number of fossils were collected at these localities during our fieldwork in February 1999.The most extensively examined areas were Mae Soi and Sob Mae Tham, where we recognized 17 and 20 fossil localities, respectively. Our field survey suggests that there is still a good possibility to find new fossil sites in northern Thailand. In this article, we provide field information on each of these fossil localities
