==Discovery and naming== Ratchasimasaurus was initially known as the "Probactrosaurus-like" iguanodontian and is only known from the holotype (specimen NRRU-A2064), a complete left dentary with no teeth that was found in the Khok Kruat Formation in Thailand by a local farmer near a pond, likely around ; NRRU-A2064 was mentioned by Norman in 2004 in a phylogenenetic analysis. The genus was named in 2011 by Shibata, Jintasakul & Azuma. The holotype is currently housed in The Northeastern Research Institute of Petrified Wood and Mineral Resources (NRIPM) and a mounted skeleton exists in River City, Bangkok.
