It likely weighed at least 10 tonnes more than Dippy the DiplodocusThitiwoot Sethapanichsakul, lead researcher“Our dinosaur is big by most people’s standards – it likely weighed at least 10 tonnes 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.
The creature, named Nagatitan chaiyaphumensis after a snake from Southeast Asian folklore and the province of Chaiyaphum where it was found, weighed as much as nine adult elephants.
Thitiwoot described the sauropod as “the last titan” because it was excavated in one of the youngest rock formations where dinosaurs were found in Thailand, Agence France-Presse reported.
He said the region later became a shallow sea, “so this may be the last or most recent large sauropod we will find in Southeast Asia”.
