In 2022 and 2023, researchers with the National Center for Wildlife in Saudi Arabia were making their rounds through caves near the northern city of Arar — standard survey work, looking for signs of living wildlife. What they found instead was something the scientific world had never documented before: seven cheetahs, naturally mummified by the cave environment's hyper-arid conditions, soft tissue and skeletons still largely intact.

Cheetahs had been declared locally extinct across the Arabian Peninsula back in the 1970s. Finding bodies this well-preserved — some only about a century old — already would have been remarkable. But the DNA locked inside those remains was about to reveal something even more unexpected.

When researchers extracted complete genome sequences from three of the seven mummies — the first time DNA has ever been pulled from naturally mummified cheetahs or large felines anywhere — what they found stopped them cold. Two of the oldest specimens weren't genetically closest to the Asiatic cheetah as expected. They matched the Northwest African cheetah, a subspecies called Acinonyx jubatus hecki, native to a region thousands of miles away.

That meant at least two distinct cheetah subspecies once roamed the Arabian Peninsula — not one. The findings were published in the journal Communications Earth and Environment. Lead researcher Ahmed Al Boug of the National Center for Wildlife called it 'highly surprising,' noting it represented the first documented case of natural mummification in cheetahs and the first physical proof that multiple subspecies had crossed this landscape.

Two Subspecies. One Peninsula. Totally Different Origins.

How Well Do You Know This Discovery?

Four questions. The answers might surprise you.

How many of the seven mummified cheetahs had their DNA analyzed for this study?

• All seven — Not all seven — researchers analyzed three, extracting complete genome sequences. The remaining mummies and skeletal fragments are still being investigated.
• Three — Correct. Three of the seven mummies yielded complete genome sequences — the first time DNA has ever been extracted from naturally mummified large felines.
• Five — Five skeletal remains were dated, but only three mummies had their DNA extracted and analyzed. Those three delivered the key subspecies findings.
• Two — Two of the oldest specimens turned out to be genetically closer to the Northwest African subspecies — but three mummies total were used for DNA analysis.

How old is the oldest skeletal remain found alongside the mummies in the Saudi caves?

• About 500 years old — The oldest remains go back much further — about 4,000 years, showing cheetahs used this landscape across thousands of years of human history.
• About 1,000 years old — The oldest dated remains are roughly 4,000 years old — placing these cheetahs in the Arabian Peninsula during the Bronze Age.
• About 4,000 years old — Exactly right. Five skeletal remains were dated; the oldest clocked in at approximately 4,000 years — evidence of a cheetah presence spanning millennia.
• About 10,000 years old — The oldest dated remains are about 4,000 years old. Two of the analyzed mummies are far more recent — dating from roughly 130 to 1,870 years ago.

What did researchers find unusual about the cheetahs' use of the caves, beyond the mummification itself?

• Cheetahs almost never use caves — it's extremely atypical behavior — Correct. Al Boug described cave use by cheetahs as 'extremely atypical behavior,' adding another layer of mystery — researchers are still investigating why they were there and don't believe it was accidental.
• The caves were too small for cheetahs to enter naturally — Size wasn't the noted mystery. The unusual element was behavioral — cheetahs rarely if ever use caves, making their presence there a puzzle the team is still working to explain.
• The caves showed signs of human use at the same time — The article doesn't report shared human use as the unusual element. The striking anomaly is that cave-dwelling is essentially unheard-of behavior for cheetahs.
• Only juveniles were found, suggesting parents abandoned cubs there — Actually, both young animals and adults were found — suggesting cheetahs were breeding and thriving in the area, not abandoning cubs. The cave behavior itself, across multiple ages, is the puzzle.

Why do researchers say this discovery specifically helps future cheetah reintroduction efforts in the region?

• It proves the landscape can currently support cheetah populations — The discovery is about the historical record, not current conditions. It identifies which subspecies actually lived and bred there — so any reintroduction can use ecologically appropriate animals rather than bringing in cheetahs from completely different environments.
• It identifies which subspecies actually lived and thrived there, so reintroduction can use the right lineages — That's the key finding. Because both subspecies are now documented in the historical record — with evidence of breeding, not just passing through — reintroduction can focus on animals that are ecologically appropriate to that specific landscape.
• It provides living tissue samples that could be used for cloning — The article doesn't mention cloning. The value is genetic identification — knowing which lineages once thrived there means conservationists can make evidence-based decisions about which cheetahs to reintroduce.
• It shows the caves themselves could serve as protected habitat — The caves' role in any reintroduction plan isn't the point — in fact, cave use is described as abnormal behavior. The breakthrough is the genetic evidence of which subspecies lived, bred, and survived in the broader landscape.

The presence of young animals alongside adults in the caves is one of the most important details in the whole study. It tells researchers these cheetahs weren't just migrating through — they were raising cubs, establishing territory, and building populations across a landscape that now looks radically different from the thriving ecosystem it once was.

That landscape connection matters because gazelles — a primary prey species for cheetahs — are currently being restored in Saudi Arabia. The conditions that once supported full cheetah populations may be slowly coming back. The DNA evidence tells scientists not just that cheetahs belonged there, but specifically which animals, genetically speaking, would be coming home.

A Timeline Written in Bone and DNA

• ~4,000 years ago — Oldest cat remains in the Saudi caves were alive
• ~1,870 years ago — Earlier boundary of the two analyzed mummies' date range
• ~130 years ago — More recent boundary — cheetahs still present far more recently than assumed
• 1970s — Cheetahs declared locally extinct across the Arabian Peninsula
• 2022–2023 — National Center for Wildlife researchers discover 7 mummified cheetahs in 5 caves near Arar, Saudi Arabia
• January 2025 — DNA findings published in Communications Earth and Environment — two subspecies confirmed

The Discovery by the Numbers

• 7 — Mummified Cheetahs Found
• 54 — Additional Cat Skeletal Remains
• 2 — Subspecies Now Confirmed
• 9% — Historic Range Remaining

Adrian Tordiffe, a veterinary wildlife specialist and lecturer at the University of Pretoria in South Africa, called the Arabian Peninsula a 'natural bridge for cheetahs, not an ecological dead end' — a framing that flips how scientists have long thought about this region's role in cheetah history. The peninsula wasn't a marginal zone where a few cheetahs wandered and disappeared. It was a corridor, a crossroads, a place where lineages from different corners of the continent met and survived for thousands of years.

That realization — built entirely from DNA extracted in a lab from bodies found in a desert cave — is what conservation science looks like at its most powerful. A discovery no one was looking for, unlocking a plan that didn't exist before.

What This Discovery Actually Proves — and What It Doesn't

Only one cheetah subspecies ever lived in Saudi Arabia.

Verdict: false

This was the scientific consensus before the study. DNA from three mummies confirmed that at least two subspecies — the Asiatic cheetah and the Northwest African cheetah — once lived on the Arabian Peninsula.

The cheetah mummies represent the first documented natural mummification of cheetahs.

Verdict: true

Lead researcher Ahmed Al Boug confirmed this is the first documented case of natural mummification in cheetahs, and the first time DNA has been extracted from naturally mummified large felines.

Cheetahs in the region were only passing through — they weren't established populations.

Verdict: false

The remains include both young animals and adults, indicating the cheetahs were breeding and thriving — not simply migrating through. Researchers say the landscape once supported full cheetah populations.

The cave discovery is consistent with typical cheetah behavior.

Verdict: false

Cave use by cheetahs is described as 'extremely atypical behavior.' Researchers are still investigating why the animals were there, and do not believe it was accidental or related to end-of-life isolation.
