The discovery of a indurate mud carapace wrapped around a 3,200 - year - old mummy has brought a previously unknown ancient Egyptian burial practice to light .

The mud shell — a scale - like case — was identified on an Egyptian momma keep at the Chau Chak Wing Museum at the University of Sydney in Australia . shell on mummies have been document before , but they ’re made from resins or a compounding of resins fuse with other substances , such as bitumen , explained Karin Sowada , the trail source of the new study and an archeologist from Macquarie University , in an electronic mail . Her newpaper , published today in PLOS One , draw the first known ancient Egyptian cuticle made from mud .

“ Our multi - corrective study thus provides new insight into this case of dry gangrene procedure and dilate our understanding of the way ancient Egyptians treat their dead , ” said Sowada . “ Due to mud being a more affordable and readily usable option to resin , it is indicate that this cold gangrene technique is likely to have been more common than antecedently thought . Further probe of other non - regal mummify individual will reveal the extent to which this technique was practiced . ”

This mummy has a bit of a weird backstory , resulting in a second authoritative discovery . Australian pol and philanthropist Charles Nicholson purchased the mama in the mid 1850s and donated it to the University of Sydney in 1860 . lettering and symbol on the coffin suggested the name “ Meruah ” for the occupier and a burial date of around 1000 BCE . As it change by reversal out , however , neither of these things are unfeigned , as the body does n’t actually belong to the casket , according to the new research .

In 1999 , scientist used CT CAT scan to dissect the mummy , during which time they detected the carapace . A re - investigating of the mummy commenced in 2017 in preparation of the opening of the Chau Chak Wing Museum . update CT scans were made of the soundbox , along with a novel analytic thinking of sample taken from the mummy , “ allowing for a more elaborated discernment of the carapace layer , ” said Sowada .

Radiocarbon dating suggests the body , go steady to the 12th century BCE ( circa 1200 to 1113 BCE ) , is actually older than the casket . A likely scenario is that nineteenth - century dealers put the momma in some random coffin to make a complete set , and then sold it to Nicholson . The name “ Meruah , ” therefore , and a number of titles , including “ Chantress of ( the god ) Amun , ” are probably not precise to this someone .

The new scan also confirmed the eubstance as belonging to a fair sex who died between the geezerhood of 26 and 35 . The updated depth psychology shed new light onto the carapace , unwrap it as a harden shell wrapped around the consistency and packed within the linen paper wrappings . Aside from this , not much else is known about the woman , but the nature of her interment provides some clues .

“ give the overall timbre of her mummification and the added expense of the carapace to restore the dead body at some tardy point , we can say that she was likely a person from a family of mean , ” explained Sowada . “ However , the use of mud to make a carapace , rather than fine exported resin as can be seen with some mummified royal individual of the catamenia , suggests a more economic approaching by those who carried out her post - mortem intervention . ”

As the CT scan also demonstrate , the trunk appears to have been damaged shortly after dry gangrene , which likely prompted the mud - based coating .

“ The luck of this damage are unidentified , ” said Sowada , who explained that “ this clay carapace , together with some rewrapping and wadding of the body with linen paper , would have served to reform and protect the damaged body . ”

Indeed , this would ’ve been very important to the ancient Egyptians , who associated the preservation of the deceased with their continued universe in the afterlife . And as Sowada pointed out , “ clay itself was associated with the idea of re-formation and growth , so it would have been a symbolically important stuff to habituate for this repair , as well as cheap . ”

Meruah , or whatever her name is , is now on display at the Chau Chak Wing museum . Excitingly , visitors can consider a 3D visualisation of the mummy , in which they can move through and investigate the different layers , including the clay carapace .
