Fork formation and other signs of osteophagia on a long bone swallowed by a red deer stag (Cervus elaphus)

A right anterior cannon bone (os metacarpale 3 + 4) of a red deer that was found in the reticulum of a 7-year-old red deer stag is described. The bone, which had accidentally been swallowed by the stag, showed clear signs of bone chewing (osteophagia), the most prominent being the formation of a fork at its distal end. Knowledge of the possible bone changes brought about by ruminant osteophagia may prevent the erroneous interpretation of skeletal remains as being worked by hominids.
