In 1989, Fukuisaurus remains were found in Katsuyama in Fukui Prefecture. They were found in rocks of the Kitadani Formation dating back to the Barremian. Yoshitsugu Kbayashi and Yoichi Yamama described the type species Fukuisaurus Tetoriensis in 2003. Fukui is the genus name. The specific Tetori Group name is Fukui. Type specimens or cotypes include FPDM–V-40-1, a right maxilla and FPDM–V-40-2, a left jugal. Additional elements from a skull as well as a right-sternal plate were also found. Many skeleton elements have been discovered since 2003, with more detailed finds.

Fukuisaurus was an ornithopod that was relatively small. Gregory S. Paul, in 2010, estimated that Fukuisaurus measured 4.5m in length and weighed 400kg. It was a bipedal and optionally quadrupedal animal. Its general build was similar to Altirhinus, Ouranosaurus, and Iguanodon. Fukuisaurus, according to the description, was unique in that its skull wasn’t kinetic. The tooth-bearing maxilla and vomer would be so fused that it would have made sideways chewing impossible.
