THAILAND'S northeastern region has seen civilizations come and go over the centuries. In the 1970's, an archeological excavations at Ban Chiang, 50 kms cast of Udon Thani, unearthed the remains of a Bronze Age civilization that flourished over 5,000-7,000 years ago. A thousand years ago, the area was also part of the ancient Khmer empire that gave birth to Angkor Wat. The Khmer ruins at Phimai and Phanom Rung are fine examples of this great civilization that preceded Sukhothai-Thailand's first established capital.

But even before human begins roamed the plateaus of "Isan", the region was once home to a more ancient species of animal-the dinosaur. The discovery of new dinosaur bones at the Phu Wiang National Park in Khon Kaen province has brought excitement to the world at large. Thai people are even more excited to learn that the fossils are the "grandfather" of all tyrannosaurs, the oldest example of the fierce, mcat-eating dinosaur ever found.

The discovery was reported by a team of Thai and French researchers. The report has just been published in the well-known science journal "Nature". Researchers have named this new species of dinosaur the Siamotyrannus isanensis. It is 20 million years older than earliest known Tyrannosaurus rex, the feared beast of the popular movie "Jurassic Park". The meat-eating dinosaur was first found at the Phu Wiang National Park in Phu Wiang district,Khon Kaen province in 1987. The study on its hip bones, spine and legs was completed early this year and published in the latest issue of the journal "Nature".
The Department of Mineral Resource says the new dinosaur found in Thailand is only 6.5 metres longs, about half the size of the Tyrannosaurus rex. The excavation and study on the fossils of this dinosaur were conducted through cooperation between Thailand's Department of Mineral Resources and the University of France. The project started in 1979, and a plant-eating dinosaur was discovered in Phu Wiang in 1984 . It was named Phuwiangosaurus sirindhornae in honuor of Her Royal Highness Princess Maha Chakri Sirindhorn.
The new discovery of dinosaur fossils in Phu Wiang has made a name for Thailand. It may prove that this tyrannosaur evolved in Asia and spread to North America. The story of dinosaurs has always attracted people of all ages and nationalities. The first dinosaurs fossils were found about 175 years ago in Connecticut,USA. Since then, a great many others have been found in other parts of the world. These fossils are mainly dinosaur bones, teeth and eggs. Scientists can put the bones together into whole skeletons and from the skeletons they can tell what the dinosaurs actually looked like. By studying fossil teeth, scientists can tell whether a dinosaur ate plans or meat. Meat eater has pointed, sharp teeth for teaching meat. Dinosaurs that ate plants had flat, blunt teeth designed for chewing.
The Tourism Authority of Thailand, the Department of Mineral Resources and other agencies concerned are joining hands in establishing a dinosaur museum will be completed by the year 2,000. When completed, the museum will become a tourism attraction in Khon Kean. It will also serve as a study centre for these who are interested in the ancient dinosaurs, which died out millions of years before the first humans appeared on Earth.
