The bones of most body parts and some front and back fins of Hobetsu Araki Ryu, popularly known as “Hoppy,” were collected in the Hobetsu area. The systemic skeleton of a plesiosaurus (total length of 8 m) is the second sample found in Japan after those of Futaba Suzuki Ryu discovered in Fukushima in 1968.
