Ichnotaxonomic revision of dinosaur tracks from the Lower Cretaceous Tetori Group, Japan.
Memoir of the Fukui Prefectural Dinosaur Museum 18: 1-20Â
Recently, ichnotaxonomic description and comparison of dinosaur tracks were developed by objective and quantitative analyses using three-dimensional digital data. However, many dinosaur tracks from the Tetori Group discovered in the 1990's were described on the basis of classical methods. We developed ichnotaxonomic descriptions for 14 dinosaur tracks from the Tetori Group in the Kuzuryu and Shiramine areas from objective and quantitative analyses. Our assessments of the 14 tracks identified five theropods and seven iguanodontids as trackmakers. Ichnotaxonomic comparisons show that the theropod tracks include the ichnofamilies Grallatoridae and Eubrontidae, and the iguanodontid tracks include the ichnogenera Caririchnium and Amblydactylus. The Tetori Group has yielded dinosaur tracks from at least three different horizons, and we subdivided this ichnoassemblage into the Itsuki, Akaiwa, and Kitadani dinosaur ichnofauna on the basis of the depositional age. These dinosaur ichnofaunas are dominated by theropods and iguanodontids; however, the ichnofaunal diversity of the Itsuki dinosaur ichnofauna is lower than those of the Akaiwa and Kitadani dinosaur ichnofaunas. This difference is probably related to depositional environments.
