This is a horn cup with an animal-shaped decoration. A large number of these earthenware cups dating back to the Three Kingdoms Period have been excavated around the Nakdonggang River, including Gyeongju, Gimhae, Busan, Changnyeong, and Dalseong. There is an animal-shaped decoration on the foot, and the horn cup is attached on the back of the animal. The exact excavation site of this cup is unknown, but considering the shape of the foot, it is presumed to have been made in Gaya.
