The motivation for such an effort was because of the similar age of rocks in Suranaree Subdistrict, Nakhon Ratchasima Province, Thailand and Katsuayama, Fukui Prefecture, Japan. Similar dinosaurs are known from the formations of both locales, and so the researchers wanted to collaborate in research to be able to more deeply compare the prehistory of both countries. The collaboration was approved as the Japan-Thailand Dinosaur Project (JTDP), and this contributed to the basis of the founding of the Asia Dinosaur Association in 2013, by which time over 30,000 fossils had been found by the joint effort.
