Abstract

A new hybodont assemblage was found in Cretaceous freshwater sediment of Peninsular Malaysia. This is the first discovery of Mesozoic nonmarine fishes from Malaysia. A faunal comparison with the Khorat Group has also been carried out. Approximately 100 specimens were prepared and examined in this study. The Malaysian material provides a finer understanding of morphological variation in the teeth of freshwater hybodont sharks from Southeastern Asia, as well as of their distribution. It points out for the first time to a biostratigraphical correlation between the Cretaceous freshwater deposits in Peninsular Malaysia with those of the Khorat Group in Thailand.
