Pretty cool. Estimated 2400 year old Greek trading vessel. Remarkably intact due to lack of oxygen at the depth it was found. There is a cool video from a submersible that circles the wreck. Pretty amazing:

Radiocarbon dating shows that the wooden vessel dates to 400 B.C., around the time the Greeks invented the catapult and North America's Olmec culture was dying out. It was found off the coast of Bulgaria in late 2017 after lying undisturbed on the seafloor for more than 2,400 years.
