They determine the species of a two-meter fish found on a shipwrecked king of Denmark 525 years ago

The animal, whose bones were discovered among the wreckage of the Gribshunden ship in the western Baltic, was very rare in this sea and must have served as a "propaganda tool" for the power and wealth of John I of Denmark. Lund University in Sweden, published in the Journal of Archaeological Science has concluded that a large fish whose remains were found in a shipwreck in the late 15th century was a sturgeon.
