Scientists have identified a massive new dinosaur from remains discovered in Thailand, with the creature estimated to have weighed as much as nine adult elephants.The long-necked herbivore stretched 88 feet and weighed about 27 tons, according to a study published in the journal Scientific Reports.It probably roamed what is now Thailand between 100 million and 120 million years ago and is the largest ever found in Southeast Asia, researchers said.They estimated the new dinosaur had the same heft as nine adult Asian elephants."Our dinosaur is big by most people's standards — it likely weighed at least 10 tons more than Dippy the Diplodocus," said lead researcher Thitiwoot Sethapanichsakul, referring to the enormous composite cast previously on display at London's Natural History Museum.
