A new vertebrate fossil site, “Phu Sung” in Sakon Nakhon Province was discovered.
Various vertebrate fossils belonging to fresh water shark, bony fish,
turtle, crocodile and dinosaur were found in reddish silty mudstone of the
Early Cretaceous Sao Khua Formation of the Khorat Group. Crocodilian remains
including a complete skull and partial articulated skeleton are very well
preserved associated with turtle remains. Moreover, well preserved 19 turtle
shells were found accumulated together. These discoveries will certainly fulfill
our knowledge about these aquatic taxa from the Early Cretaceous Sao Khua
Formation. The exceptional preservation of Phu Sung fossils could probably
relate to the paleoenvironment in the Early Cretaceous of Thailand.
