Professor Tokio Shikama from Yokohama National University was convinced the remains were of a supposedly extinct plesiosaur. Dr. Fujiro Yasuda from Tokyo University of Marine Science and Technology agreed with Shikama, "the photographs show the remains of a prehistoric animal". Dr. Fujiro Yasuda summarizes his observations in newsreel from the time of the discovery. Yasuda and Taki, icthyologists, disputed that the cryptid could be a shark which would necessitate Michihiko Yano was mistaken when he claimed to observe two dorsal fins.
