In 1994, a new dinosaur site was discovered at Phu Kum Khao, a small hill in Sahatsakhan District, Kalasin Province. Over 800 skeletal elements have been found there, belonging to at least seven individual from two general of sauropod dinosaurs. One of the specimens is the most complete dinosaur skeleton found to date in Thailand. These sauropod dinosaurs died about 130 million years ago. Their bones are associated with two kinds of theropod dinosaurs teethe and with crocodile, turtle, fish and mollusk fossils, thus strongly suggesting that these sauropods were buried in sediments of a large river. This dinosaur site is now protected under a permanent building which also displays exhibits about the discovery of the site.
