Researchers "shocked" to discover 2,000-year-old Egyptian mummy was a pregnant woman

Researchers examining an ancient Egyptian mummy thought that they were looking at the body of a male priest. Instead, they were shocked to discover the body was actually a woman — who had been seven months pregnant at the time of her death. 

According to a new study in the Journal of Archaeological Science, X-rays and computer tests finally revealed the mummy's true identity, showing the small hands and feet of a fetus. Researchers in Poland said it's the first and only known case of a well-preserved mummified pregnant woman. The mummy dates back to the first century B.C. and is believed to come from royal tombs in Thebes in Upper Egypt. It first arrived in Warsaw in 1826.
