The whale bones were discovered in mid-April south of Skee in the municipality of Strömstad in conjunction with excavations for the E6 extension. The whale skeleton, which is between 15 and 20 metres and is almost intact, has now been studied by Thomas Dahlgren at the Department of Zoology, University of Gothenburg, who can confirm that it is a right whale.

There are currently four species of right whale. What is particularly interesting is that the size and shape of the whale bones resemble those of a fifth species: the mystical “Swedenborg whale”, first described by the scientist Emmanuel Swedenborg in the 18th century.

-Bones from what is believed to be Swedenborg’s right whale have previously been found in western Sweden. However, determining the species of whale bones found in earth is complicated and there is no definitive conclusion on whether the whale actually existed, it could equally well be a myth, says zoologist Thomas Dahlgren and his colleague Leif Jonsson.

To determine the species of whale that has been found Thomas Dahlgren has conducted DNA tests that are to be analysed in conjunction with researchers at the Natural History Museum in London. The whale bones are interesting in several respects. The fragments of bone were collected in a clay deposit and remains of marine organisms that today are also endangered species were found around them.

– The hunt for the large whale species, which led to the extinction of the Atlantic grey whale and perhaps the Swedenborg whale, may also have caused the extinction of a large number of species that are dependent on whale carcasses for their survival, says Thomas Dahlgren.

The whale bones are thought to be around 10,000 years old and were found 75 metres above sea level, but in a site that at that time was located out on the coast. It is conjectured that the bones have been preserved for such a long time as they were surrounded by fine, oxygen-free clay. The largest whale bone, approximately 2.5 metres long, is part of a jawbone. Among the smaller bones is a vertebra. Discussions are underway on whether the bones can be put in order and potentially put on public display.

Facts about the Swedenborg whale (Balaena swedenbo´rgii)
The whale species is believed to have existed in the North Sea from the period when the inland ice melted until about 8,000 years ago, and subsequently to have died out. Ten collections of bones from the species have been found in the west of Sweden. However, there is speculation that the bones have been mistaken for other species, and that the Swedenborg whale never existed. Source: Swedish National Encyclopedia
