Animal mummy 'secret' revealed
Scientists studying animal mummies from Ancient Egypt have found that lots of them don't actually contain any animal remains.
Researchers at the University of Manchester scanned more than 800 animals mummies to see what was really hidden beneath the bandages.
About a third contained complete animal remains, a third had bits of animal remains and the rest were empty, filled with things like mud, eggshells and nest material instead.
But the researchers don't think it was done as a scam. Those buying them may have known they weren't complete mummies.
Instead they think there was such a high demand for mummified animals in Ancient Egypt, that the makers resorted to using other things instead.
