When the skulls were discovered in a museum in 1870, the story of their origins was still shrouded in mystery.

Now, new research by archaeologists has shown that the skulls had the most bizarre features: Their faces were made of skull bones, and they were mostly female.

“We were very surprised to find that these skulls are all female,” archaeologist Dr. Jonathan Fink said in a press release.

“And we were also surprised that these skeletons had the bizarre features of skullbones.”

Researchers first discovered the skulls in 1871, and discovered more than 200 skulls in the first 100 years of the 20th century.

These were the first of the mysterious skulls to be discovered in Europe, but were not all from the same time period.

“The skulls were the result of an enormous number of people coming together,” Fink told The New York Times.

“It’s kind of like the first wave of the Industrial Revolution, with the industrialization of Europe.”

The skull bones had been deposited in a graveyard in the small town of Morinheim, in the eastern state of Saxony.

Fink and his team set out to find the skeletons, but they found them all in the same place.

“They were very well preserved,” Finks told The Associated Press.

“They were all pretty well preserved, so the only thing you can do with them is to try to get them into an X-ray machine.”

Fink said that the skull bones have a long history of use in archaeology, and that their shape and size have been the subject of debate.

“I think that what’s going on is that these were not just some isolated individual individuals, but there were thousands of them,” Finkle said.

“We were looking for a population of these, and there were hundreds of thousands of people living around these sites.”

Finks and his colleagues have already identified hundreds of these skeletons from Morinheimer, but are now working on identifying the skulls of the people who actually made them.

“In order to make sure we can really understand the relationships and the social interactions that occurred in this community, we have to make certain that we can identify the people that made these skeletons,” Finker said.

Fink is not the only researcher who has made this type of research on the skulls.

“The skull was not only the most intriguing of all the skulls, it was the only one that we found,” Fisch said.
