Scientists recently used 3-D imaging technology to look inside the mummies of a cat, bird, and snake. The research is helping experts learn more about how ancient Egyptians treated animals. Researchers said last week that they used a special technique, X-ray micro CT scanning, to look inside the mummies. The scanning process permits the scientists to study the mummies while keeping them whole. The CT scans were much more detailed than medical CT scans. The researchers published their findings in the journal Scientific Reports. Ancient Egyptians mummified not only humans but also many animals including cats, dogs, birds, snakes and crocodiles.
