The Tetori Group is a stratigraphic group in Japan, found within several basins in and around Fukui Prefecture. It is Early Cretaceous in age. It primarily consists of freshwater continental deposits, with some beds of volcanic tuffite. It primarily overlies Jurassic marine sediments or gneiss basement. Some of the units within the group are noted for their fossil content, including dinosaurs, lizards mammals and other vertebrates.
