This is amazing!
British archaeologists unearthed a 2000-year old skull with a well-preserved brain which according to them was the oldest in Britain. They found it while digging in a muddy pit at the University of York in England. They believed that it was severed from its owner sometime before the invasion of Britain by the Romans.

Officer Rachel Cubbitt felt something moved inside the cramium, and when she looked at the base of the skull, she found a yellow substance inside and was confirmed as a brain tissue when scanned at York Hospital.

Richard Hall, a director of York Archaeological Trust, said it's unclear that the brain had survived for centuries and wondered why the skull is separated from its body.
