Xibaar yu neex
Sirindhorna is known from a nearly complete skull and lower jaws, which is very rare for dinosaurs from Southeast Asia.2
It had a long ridge on top of its skull called a sagittal crest, which helped anchor strong jaw muscles.2
Its teeth had a main ridge and a secondary ridge, which helped grind plant material.2
The fossils were found by farmers digging a reservoir, and then scientists studied the site.1
Sirindhorna lived in a semi-arid environment with meandering rivers, about 120 million years ago.2
It is one of the most primitive members of the group Hadrosauroidea, which includes the duck-billed dinosaurs.2
