H5N1 tiny Egyptian mummy long believed to endure that of a hawk is truly a rare instance of a near-to-term, severely malformed fetus, says an bear witness led past times mummy skillful Andrew Nelson of Western University inward London, Canada.

Its misidentification inward the Maidstone Museum inward the UK, every bit 'EA 493 - Mummified Hawk Ptolemaic Period', came to lite inward 2016 when the museum decided to CT-scan its resident woman individual mummy and, incidentally, to scan 'EA 493' too other beast mummies at the same time. That's when the smaller mummy surprised experts, who identified it every bit a human fetus. But the CT scans lacked item too Nelson worked alongside the Museum too Nikon Metrology (UK) to comport a micro-CT scan: an extremely high-resolution scan that didn't entail damaging the mummy inward whatever way.
Nelson too then assembled an interdisciplinary squad to examine too translate the images inward what has locomote the highest-resolution scan always conducted of a fetal mummy.
The images demo well-formed toes too fingers but a skull alongside severe malformations, says Nelson, a bioarchaeologist too professor of anthropology at Western. "The whole locomote past times role of his skull isn't formed. The arches of the vertebrae of his spine haven't closed. His earbones are at the dorsum of his head."
There are no bones to shape the wide roof too sides of the skull, where the encephalon would unremarkably grow. "In this individual, this role of the vault never formed too in that place in all probability was no existent brain," Nelson says.
That makes it 1 of only 2 anencephalic mummies known to be (the other was described inward 1826), too past times far the most-studied fetal mummy inward history.
Nelson latterly presented the team's findings at the Extraordinary World Congress on Mummy Studies inward the Canary Islands.
The inquiry provides of import clues to the maternal diet - anencephaly tin number from lack of folic acid, flora inward greenish vegetables - too raises novel questions virtually whether mummification inward this instance took identify because fetuses were believed to accept to a greater extent than or less ability every bit talismans, Nelson says.
"It would accept been a tragic 2nd for the identify unit of measurement to lose their infant too to hand nascency to a real strange-looking fetus, non a normal-looking fetus at all. So this was a real exceptional individual," Nelson says.
H5N1 squad of to a greater extent than than a dozen researchers - specialists inward Egyptology, radiology, anatomy, neonatology too urology, from Western University to England to French Republic to Cairo - lent their expertise to the project.
