Ancient Cheetahs Unearthed in Saudi Arabia: A Glimpse into a Lost Past and Hope for the Future
Scientists have made a remarkable discovery in the remote desert caves of northern Saudi Arabia: the remarkably well-preserved remains of seven cheetahs, some dating back over 4,000 years. The uncover, detailed in a study published in Communications Earth & Environment, is rewriting our understanding of the cheetah’s historical range and offering novel hope for their reintroduction to the Arabian Peninsula.
Unexpected Finds in the Arar Caves
The cheetah remains were discovered between 2022 and 2023 during surveys conducted by the National Center for Wildlife in Saudi Arabia. Located near the city of Arar, the caves provided an unexpectedly ideal environment for natural mummification, preserving not only skeletons but also soft tissues. Alongside the seven complete mummies, researchers also unearthed the bones of an additional 54 cheetahs.
A Genetic Surprise: More Than One Cheetah Subspecies
Previously, it was believed that only the Asiatic cheetah (Acinonyx jubatus venaticus), currently critically endangered with a small population remaining in Iran, inhabited the Arabian Peninsula. However, DNA analysis of three of the mummies revealed a surprising twist. Two of the oldest specimens were genetically closer to the Northwest African cheetah (Acinonyx jubatus hecki), indicating that at least two distinct subspecies once roamed the region.
“This finding represents the first documented case of natural cheetah mummification and the first physical evidence that cheetah subspecies were present on the Arabian Peninsula,” stated Ahmed Al Boug, lead author of the study and researcher at the National Center for Wildlife in Saudi Arabia.
Why Caves? The Mystery of the Cheetah’s Shelter
Researchers are still investigating why cheetahs sought refuge in caves. It wasn’t likely accidental or a sign of end-of-life isolation. The consistent, arid conditions within the caves undoubtedly contributed to the exceptional preservation of the remains. The study suggests the caves offered a stable microclimate conducive to natural mummification.
Implications for Cheetah Conservation
The discovery has significant implications for cheetah conservation efforts. Knowing which lineages historically inhabited the Arabian Peninsula provides crucial information for reintroduction programs. Instead of introducing cheetahs from entirely different environments, conservationists can now focus on utilizing animals with a genetic heritage suited to the region.
“Now that we know which lineages of cheetah inhabited Arabia, reintroduction efforts can focus on using ecologically appropriate animals, rather than bringing in cheetahs from completely different environments,” explained Al Boug.
A Bridge, Not a Dead End: The Cheetah’s Arabian History
The findings challenge the notion of the Arabian Peninsula as an ecological dead end for cheetahs. The presence of multiple subspecies over millennia suggests it was, in fact, a vital corridor for their movement and dispersal. This historical connection strengthens the case for successful reintroduction.
“This tells us that the Arabian Peninsula was once an important natural bridge for cheetahs, not an ecological cul-de-sac,” said Adrian Tordiffe, a wildlife veterinarian based in India, who was not involved in the study.
Restoring a Lost Ecosystem
Historically, wildlife populations in the Arabian Peninsula declined due to human impact, including overhunting and land-utilize changes. However, with the establishment of large protected areas and reduced threats like habitat degradation, the region is becoming increasingly conducive to wildlife recovery. The reintroduction of cheetahs, a top predator, is seen as a key step in restoring the ecological balance.
“Cheetahs and other top predators play important roles in the ecosystem. Cheetahs are large hunters, quickly consuming their prey and leaving remains that feed other species. Where we find large predators, there is greater biodiversity,” noted Laurie Marker, founder and executive director of the Cheetah Conservation Fund.
