In a groundbreaking discovery, researchers have unearthed the remains of 61 cheetahs hidden deep within caves in northern Saudi Arabia. These naturally mummified and skeletal remains provide valuable insight into the historical presence of these big cats in the Arabian Peninsula. The findings, published in the journal Communication Earth & Environment, shed light on the distribution and evolution of cheetah populations in the region.
Lead author Ahmed Boug, who is the general director of the National Center for Wildlife in Riyadh, revealed that the cheetahs found in the caves lived between 49 and 188 years ago. This discovery supports ongoing efforts to reintroduce modern-day cheetahs to the region as part of rewilding initiatives. Of the 61 cheetahs discovered, seven were naturally mummified, preserved by the arid conditions of the Saudi Arabian desert.
Carbon dating of the specimens revealed a wide range of ages, with the oldest cheetah having lived around 4,000 years ago and the youngest approximately 130 years ago. Furthermore, genetic analysis of three samples indicated a shift in the dominant cheetah subspecies in the region over time. While older remains were more closely related to a Northwest African subspecies, more recent specimens showed genetic similarities to the Asiatic cheetah, which is now predominantly found in Iran.
Boug expressed surprise at these findings, as previous assumptions suggested a closer relationship between Saudi Arabian cheetahs and the Asiatic subspecies. The research team is continuing to investigate the geographic and genetic implications of these discoveries to unravel the complex history of cheetah populations in the region.
The study also highlighted the potential role of human activities in the decline of cheetah populations in Saudi Arabia. Boug pointed to factors such as poaching, industrial development, and urban expansion as contributing to the disappearance of these majestic predators from the landscape. By understanding the historical presence of different cheetah subspecies in the region, researchers hope to inform future conservation and reintroduction efforts.
Overall, the discovery of these well-preserved cheetah remains offers a glimpse into the ancient history of these big cats in Saudi Arabia. By studying their genetic diversity and distribution, researchers aim to pave the way for the reintroduction of cheetahs to the region and promote biodiversity conservation efforts.
