Tiny coffin reveals youngest preserved fetus from ancient Egypt
British archaeologists revealed this week that a miniature coffin under their care contained the youngest human fetus ever uncovered in ancient Egypt.
"This discovery is the only academically verified specimen to exist at only 16 to 18 weeks of gestation," University of Cambridge said in a statement.
The coffin made of cedarwood dates to around 664-525 BC, and highlights the value of burial rituals in ancient Egypt, even at such a young age.
