The Futaba Group is a Late Cretaceous geologic group in Japan. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[1] It consists of both fluvial and shallow marine sediments.[2] The plesiosaur Futabasaurus was found in this unit (specifically the Tamayama Formation).
