In Depth

       Fukuisaurus was initially only known from partial skull fragments,‭ ‬including a maxilla and jugal from the right hand side of the skull.‭ ‬Further specimens have since been discovered leading to Fukuisaurus being reconstructed with a strong degree of confidence. As an ornithopod,‭ ‬Fukuisaurus is similar to others of the group such as Iguanodon.‭ ‬However,‭ ‬Fukuisaurus does appear to be a more primitive form with a skull that does not support side to side chewing.
