"This is the first mummy of its kind discovered," Francine Margolis, who led a study on the mummified remains, told LiveScience .
She performed a CT scan on the mummified woman's remains to obtain pelvic measurements to confirm the cause of death.
Margolis and George Washington University anthropologist David Hunt then examined X-rays of the remains and were surprised to see a second fetus, Margolis said.
The second fetus' position inside the woman's chest cavity is also a mystery.
The X-ray images showed researchers the second fetus more clearly than the CT scans.
