2,700-year-old petroglyphs depicting people, ships and animals discovered in Sweden

The newly found petroglyphs from Sweden include depictions of humans. Here we see one tall human with their arms throw up in the air.

On a steep rock face in western Sweden, researchers uncovered a fascinating find: around 40 petroglyphs — depicting ships, people and animal figures — dating back around 2,700 years. 

The petroglyphs were carved on a granite rock face that was once part of an island, meaning people would have had to make the carvings while standing on a boat, or from a platform constructed on ice, said Martin Östholm, a project manager with the Foundation for Documentation of Bohuslän's Rock Carvings who is one of the archaeologists who discovered the petroglyphs, told Live Science.
