This week, archaeologists officially announced the discovery of a shipwreck off Spain's Mediterranean coast. Dating to the first century, the unusually large wreck -- estimated to be 100 feet long with a capacity of roughly 400 tons -- is reported to have been carrying well-preserved, 3-foot-tall clay jars used for holding fish sauce, a prized condiment for wealthy Romans. Amazingly, within the jars, archaeologists have uncovered 2,000-year-old fish bones.

Resting in only 80 feet of water, the wreck was discovered by boaters in 2000. Unfortunately, news of the wreck quickly spread, and rogue divers absconded with many of the ship's amphorae, forcing the local government to install thick metal grates over the ship to protect it. What remains of the ship lies almost entirely buried in mud. Experts believe the remaining cargo to be not nearly as exciting as 2000-year-old fish bones. Instead, they expect to find lead and copper, used for plumbing and jewelry, respectively. No word yet on whether the Romans used tartar sauce.
