Anndal belɗungal
Ratchasimasaurus is only known from a single left lower jawbone, called a dentary, which is 198.1 millimetres (7.80 inches) long.1
Its jawbone was long and flat, a unique feature that helps scientists tell it apart from other dinosaurs.12
This dinosaur lived during the Early Cretaceous period, about 121 to 113 million years ago.4
Ratchasimasaurus had both primitive and advanced features, like a backward-slanting coronoid process and a shelf between its teeth and jaw joint.12
The fossil was found by a local farmer near a pond in Thailand, likely between 2002 and 2004.1
Its species name, suranareae, honors Thao Suranari, a 19th-century war heroine from Thailand.1
