Sirindhorna is an extinct genus of iguanodontian ornithopod dinosaur from Early Cretaceous deposits of northeastern Thailand.[1]

Discovery

Sirindhorna is known from the holotype NRRU3001-166, an articulated braincase, as well as a number of other skull bones. It was collected in the Ban Saphan Hin site, Suranaree Subdistrict, Nakhon Ratchasima Province, from the Khok Kruat Formation, dating to the Aptian stage of the late Early Cretaceous, about 125-112 million years ago.[1] Sirindhorna was one of eighteen dinosaur taxa from 2015 to be described in open access or free-to-read journals.[2]

Etymology

Sirindhorna was first named by Masateru Shibata, Pratueng Jintasakul, Yoichi Azuma and Hai-Lu You in 2015. The type species is Sirindhorna khoratensis. The generic name is dedication to Princess Maha Chakri Sirindhorn for her contribution to the support and encouragement of paleontology in Thailand. The specific name is derived from Khorat, the informal name of Nakhon Ratchasima Province. [1]
