In 1545, the Mary Rose sank during the Battle of the Solent. Trapped inside the carpenter's cabin was a dog, probably kept to catch rats. Now the skeleton of the animal, nicknamed "Hatch," is on display at the Mary Rose Museum at the Portsmouth Historic Dockyard.
John Lippiett, chief executive of the Mary Rose Trust, said: "Expert analysis of Hatch's bones suggests that she spent most of her short life within the close confines of the ship."
A new museum to house artifacts from the Mary Rose is scheduled to open in Portsmouth in 2012.
