The discovery came in Seyitömer Höyük, a settlement from the Bronze Age that lies in Western Turkey.
Scientists think the person was killed in an earthquake and preserved when a fire eliminated all the oxygen in the rubble and boiled the organ inside the skull.
It’s also believed the soil lent a hand due to its high potassium, magnesium, and aluminum content. All of those substances are known to help form "corpse wax" when it’s mixed with human tissue.
While sounding really gross, the concoction is remarkably successful when it comes to preserving brain tissue.
"The level of preservation in combination with the age is remarkable," one expert noted. "If we want to learn more about the history of neurological disorders, we need to have tissue like this."
Scientists think this brain can yield priceless information about neurological disorders and their history.
Smithsonian reports it was just two years ago when a 2,600 year old brain was found in a bog.
