Scientists have identified a new species of dinosaurs in Thailand by paleontologists. They are known to be the largest dinosaurs that have been discovered in South East Asia due to their weight that can reach up to nine elephants and height of 27 meters. Long-necked plant-eating dinosaurs existed between 100 million to 120 million years ago. It is believed by scientists that discovering these dinosaurs is very exciting because during that time, there was global warming on earth.
