Abstract
The purpose of the present statement is to announce discovery of a well-preserved and potentially diverse Lower Permian ammonoid fauna from south-central Thailand. Previous Thai records of Permian ammonoids lack descriptive detail (e.g., Yanagida, 1988), but two sparse Permian occurrences from nearby areas in Malaysia have been described recently by Lee (1980). Closest similarities of the Thai material are with faunas from the Pamir (Leonova and Dmitriev, 1989) and with our undescribed collections from south Xinjiang.
