Smivs writes "The BBC report that archaeologists have found what could be Britain's oldest surviving human brain. The team, excavating a York University site, discovered a skull containing a yellow substance which scans showed to be shrunken, but brain-shaped. Brains consist of fatty tissue which microbes in the soil would absorb, so neurologists believe the find could be some kind of fossilised brain. More tests will now be done to establish what it is actually made of. The skull was discovered during an exploratory dig at Heslington Eastin, an area of extensive prehistoric farming landscape of fields, trackways and buildings dating back to at least 300 BC."
