The equivalent bone in humans is the tip of the middle finger. The "coffin bone" is supposedly so called because it is encased in the hoof like a corpse in a casket. The word "coffin" dates from the early 14th century, is French in origin, and is related to the Latin and Greek words cophinus and kophinos, meaning "basket". The word also referred to pie or pastry crust.
