Pig Remains Two dozen well-preserved animal bones have so far been found on the site. Most are legs, ribs, and skull fragments from immature pigs, and likely represented living animals kept by the pirates for food. Three cow bones, two with butcher marks, were also foodstuffs. The right ulna of a rat reflects an unwanted guest on the ship. Several other bones came from marine mammals and may be intrusive to the site. The bones are indicative of low-yield meats (like pigs' feet) and would have been pickled and served individually or used in communal potted dishes such as stews and soups or as seasonings.
