Blackbeard’s Cannon

In October 2011, a group of archaeologists discovered a 300-year-old cannon off the coast of North Carolina. The cannon was traced to the ship of the notorious pirate, Blackbeard; it is an 8-foot gun that was covered in sand and ocean debris known as concretion when it was found.
After the discovery, the archaeologists brought the ancient pirate cannon onshore, from where it was conveyed to an East Carolina University laboratory for further research. The cannon was the most remarkable discovery from Blackbeard’s ship but it wasn’t the only one as other artifacts, including an iron shackle were found.
