Scientists have made a discovery in Sweden that suggests Viking women underwent a cosmetic procedure 1,000 years ago.
A team of German researchers found three elongated skulls that were likely altered in the first year of the women's lives when their skulls were soft and pliable.
It is possible the Vikings elongated their skulls as a sign of status and beauty, the researchers said.
Cranial malformation was common in the Black Sea region and previously has only been identified in the Mesoamerican, Native American and Eurasian cultures, making this the first time it was found in the Viking people.

The researchers believe its likely that the practice of cranial modification was meant as a status symbol, showing the success the families had at trading with other regions
'We do not know where these three women grew up and where their heads were deformed,' Matthias Toplak, the co-leader of the expedition told Atlas Obscura.
'Whether their heads were deformed in their early childhood in the region around the Black Sea, for example, and how they came back to Gotland is unclear,' he added.
Researchers believe the female's skulls were likely altered in the first year of their life, when the bones were still soft enough to be changed, by wrapping bandages around the infant's head to elongate the skull.
However, if the Vikings employed more serious techniques like using weights or straps, it could have impacted their cognitive development.
The researchers clarified that they can't determine whether this was the case based on the skulls, but Jesse Goldstein, theChief of the Division of Pediatric Plastic Surgery said the more severe approach could have disastrous consequences.
'If this approach was taken, this may have had negative effects on brain function, especially if this was employed in early infancy,' he told Atlas, but added the caveat: 'It is hard to know for sure.'
Researchers believe it is more likely that artificial cranial deformation (ACD) was used to separate the women from others by showing they had traveled.
'The human body both is and represents a medium of communication,' the researchers wrote in the study, adding: 'It has an ability to produce communication in a functionally complex structured way.'
Although the women could have used ACD as a symbol of beauty, it was far more likely they 'were regarded as evidence of far-reaching trading contacts, and thus as tokens of influence and success in trading,' Toplak told LiveScience.
Researchers also found that the Vikings had filed their teeth,(pictured) and modern experiments revealed the same results could be achieved using a steel file
Researchers at the Viking Museum Haithabu and the University of Münster in Germany used DNA analysis to reveal that the skulls are from the Scandinavian Viking Age in Gotland, an island belonging to Sweden in the Baltic Sea.
Communities in Toulouse, France practiced ACD according to recordings from as recently as the early 20th century by using bands and cloths to intentionally modify children's heads - also called the 'Toulouse deformity' or 'bandeau.'
Locals in Vanuatu, a Pacific island nation, implement ACD to resemble their deity, Ambat, who has an elongated skull and a long nose.

'We elongate the heads of our children because it is our tradition, and it originates with the basic spiritual beliefs of our people,' the general of South Malakulan said on the Australian Museum website.
'We also see that those with elongated heads are more handsome or beautiful, and such long heads also indicate wisdom,' he added.
Alongside the cranial modifications, the researchers also found the Vikings employed the practice of filing their teeth which could have been used to identify certain merchant groups.
The practice might have also been administered as an initiation right and modern experiments determined that a steel file achieves similar markings as those seen in the Vikings.
Teeth filings and skull modifications have been practiced by groups worldwide including the Mayans in Mexico and the Pracas civilization in what is today Peru, between 750 BC and 100 AD.

THE VIKING AGE LASTED FROM AROUND 700–1110 AD
The Viking age in European history was from about 700 to 1100 AD.
During this period many Vikings left their homelands in Scandinavia and travelled by longboat to other countries, like Britain and Ireland.
When the people of Britain first saw the Viking longboats they came down to the shore to welcome them.
However, the Vikings fought the local people, stealing from churches and burning buildings to the ground.
The people of Britain called the invaders 'Danes', but they came from Norway and Sweden as well as Denmark.
The name 'Viking' comes from a language called 'Old Norse' and means ‘a pirate raid’.
The first Viking raid recorded in the Anglo-Saxon Chronicle was around787 AD.
It was the start of a fierce struggle between the Anglo-Saxons and the Vikings.
