Ibis Mummy
An
ibis is a bird that the ancient Egyptians considered sacred. They were
often mummified in the same way that Egyptian humans were mummified.
Harry Gove, of the University of Rochester in New York and Ann Rosalie David of the University of Manchester in England used an ibis mummy to see if it could shed light on the anomalies in the human mummy 1770 at the Manchester Museum. What they found might be relevant to the carbon dating of the Shroud of Turin.
As was the case with mummy 1770, the linen wrappings appeared to be newer than the bird they contained. And unless the bird was rewrapped—which seemed implausible to the researchers—they were confronted with an unexplained anomaly.
