概要

論文の詳細を見る
Some teeth from Shiramine, Ishikawa Prefecture, were nicknamed "Shimaryu." This enigmatic taxon was identified only as "ornithischian". These teeth are identified and described herein as terminally resorbed maxillary teeth of iguanodontids. The presence of iguanodonts in the Tetori Group suggests dispersal of the essentially European taxon to the East Asian Cratons, such as the Sino-Korean/Yangtze Cratons by Neocomian times and this also indicates a land connection via the Turgai Sea by then.
