Named By: Kobayashi & Azuma - 2003.
Classification: Chordata, Reptilia, Dinosauria, Ornithischia, Ornithopoda, Iguanodontia, Hadrosauroidea.
Species: F. tetoriensis (type).
Size: Approximately 4.5 meters long.
Known locations: Japan, Honshu Island, Fukui Prefecture, Kitadani Formation.
Time period: Barremian of the Cretaceous.
Fossil representation: Several known specimens of partial remains.
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.
