Египетийн эртний булшнаас олдсон 2500 жилийн настай матарнуудын муми шинжлэх ухааны шинэ нээлт боллоо

In the photographs, the crocodiles look almost alive. Their long, dark bodies lie across the dusty tomb floor, jaws shut and tails curled, as though the animals had wandered in from the Nile and settled down to sleep. Yet they have been dead for roughly 2,500 years, their remains preserved inside a burial chamber overlooking the river.

In 2019, archaeologists opened an untouched tomb at Qubbat al-Hawa, on the Nile’s west bank opposite Aswan in southern Egypt. Inside were ten mummified crocodiles: five bodies, some nearly complete, and five severed heads.

Crocodile mummies are hardly unusual in Egypt, but these specimens were unlike others researchers had examined. Their preservation was remarkably different, and among the remains was a species that no longer lives in Egypt.

Hidden Under an Ancient Garbage Dump

High above the Nile, the cliffs of Qubbat al-Hawa are riddled with ancient burial chambers. Egyptian nobles and priests were buried on the hillside for thousands of years, beginning more than 4,000 years ago. Archaeologists have identified about a hundred tombs there, but the crocodile burial escaped discovery largely because it had been concealed beneath centuries of accumulated rubbish.

Since 2018, a team led by Alejandro Jiménez Serrano, an Egyptologist at the University of Jaén in Spain, has been excavating a thick deposit of garbage left during the Byzantine era. Beneath the debris, archaeologists uncovered seven small tombs that ancient robbers had never entered. One contained the crocodiles, crowded together beside human burials that were considerably older.

Examining the animals called for a specialist, so the team brought in Bea De Cupere, an archaeozoologist at the Royal Belgian Institute of Natural Sciences. Her usual work involves studying scattered bones and broken fragments, making the discovery an exceptional opportunity.

“To hear you have ten crocodiles in a tomb, that’s special,” she told The New York Times. What she discovered during her examination was even more unusual than the number of animals.

Mummies Without the Usual Mummy-Making

Most Egyptian animal mummies are difficult to examine without modern imaging equipment. Their bodies were commonly wrapped in linen and coated with resin, which hardened into a protective shell. Researchers generally need X-rays or CT scans to see beneath those layers, but the Qubbat al-Hawa crocodiles had no such coating.

There was no resin, and insects had consumed nearly all the linen that once covered the remains. Only small scraps survived, along with traces of palm leaves and rope. With so little material concealing the bodies, De Cupere and her colleagues could examine the animals directly rather than relying on scans to reconstruct their anatomy.

Even their internal organs appeared to have been left undisturbed. Unlike many later Egyptian mummies, the crocodiles had not been opened and emptied during preparation. One specimen still contained gastroliths, stones that crocodiles swallow to help maintain their balance in water. Their presence provided strong evidence that the animal had never been gutted.

The researchers suspect the crocodiles underwent a much simpler mummification process. First, their bodies were buried in sand at another location, where Egypt’s hot, dry conditions gradually removed moisture from the flesh. Once sufficiently dried, the remains were dug up, wrapped and transported to the tomb. Some parts were lost before the animals reached their final resting place, while the five detached heads appear to have been separated from their bodies only after drying.

The absence of resin also helped the team estimate when the crocodiles were buried. From the Ptolemaic period onward, beginning in 332 BC, Egyptian embalmers used large quantities of resin in mummification. Because these animals showed no evidence of that treatment, the researchers place their burial before that period, probably during the 5th century BC, toward the end of the cemetery’s use.

Gifts for a Crocodile God

The reason for burying ten crocodiles together most likely lies in the worship of Sobek, the ancient Egyptian god associated with water and fertility. Often depicted with the head of a crocodile, Sobek was honored at temples throughout Egypt, where crocodiles were raised, killed, mummified and presented as religious offerings. One of his major temples stood at Kom Ombo, approximately 50 kilometers (30 miles) north of Aswan.

Most surviving crocodile mummies, however, are far smaller than those discovered at Qubbat al-Hawa. According to the team’s study, about 80 percent of roughly 300 previously examined crocodile mummies were juveniles, including many newly hatched animals. Numerous specimens now sit in museum collections with little or no information about where they were originally buried, making the archaeological context of the Aswan discovery especially valuable.

The Qubbat al-Hawa crocodiles were adults measuring approximately 1.8 to 3.5 meters (5.9 to 11.5 feet) in length. Catching animals that size would have been dangerous, particularly without modern equipment. The researchers believe the crocodiles were probably killed somewhere else, allowed to dry and eventually brought to the tomb as offerings, although precisely how they died remains unknown.

Another discovery emerged when De Cupere’s team began comparing the skulls and remaining body parts. Differences in their shapes suggested that the animals did not all belong to the same species. Closer examination revealed that the tomb contained two distinct types of crocodile, raising new questions about which animals ancient Egyptians captured and used in religious ceremonies.

Two Species, and One That Vanished

Based on the shape of the skulls and bodies, the researchers identified both the Nile crocodile (Crocodylus niloticus) and the West African crocodile (Crocodylus suchus) among the ten mummies. The second identification was particularly intriguing because scientists recognized the West African crocodile as a separate species only relatively recently. Previously, it had been grouped with its better-known Nile relative, and De Cupere’s team hopes future DNA testing will confirm the anatomical identification.

The Nile crocodile still inhabits the far south of Egypt, but the West African crocodile no longer occurs in the country. Its presence among these ancient Egyptian remains suggests that the species once shared Egyptian waters with people before eventually disappearing from the region. The discovery therefore offers a glimpse of a crocodile population that was different from the one found along the Nile today.

There may also have been a practical reason why ancient Egyptian priests preferred one species over another. Salima Ikram, an Egyptologist at the American University in Cairo who was not involved in the study, pointed to a striking behavioral difference between the two animals. Nile crocodiles are powerful, aggressive predators capable of attacking humans, whereas West African crocodiles are generally much calmer.

A person might plausibly share a pool with a West African crocodile and emerge unharmed, something considerably riskier with a Nile crocodile. For priests responsible for keeping live crocodiles in temple pools, the distinction could have mattered enormously. Animals that were easier to approach and handle would have been far more manageable during ceremonies and daily care.
