Scientists Make an Unprecedented Fossil Discovery Along South Africa’s Coast – Indian Defence Review

Scientists have uncovered an extremely rare fossil discovery along South Africa’s Cape coast, revealing traces of a mysterious prehistoric creature.
A new study has revealed an extremely rare find along South Africa’s Cape coast—fossilized burrows and tracks attributed to aardvarks (Orycteropus afer) dating back to the Pleistocene epoch. The discovery, published in Quaternary Research, represents one of the first confirmed cases of aardvark trace fossils ever identified and adds valuable data to the scarce record of prehistoric burrowing activity.
Despite being widespread across southern Africa today, aardvarks are elusive and primarily nocturnal, making direct observations difficult. Their body fossils have been found at multiple sites, but their trace fossils—including footprints and burrows—are exceedingly rare. Until now, only one unconfirmed aardvark burrow fossil had ever been suggested, located in Namibia. This new study not only confirms the presence of ancient aardvarks in coastal South Africa but also highlights the importance of trace fossils in reconstructing past environments.
Since 2008, the Cape South Coast Ichnology Project has been cataloging fossilized footprints and burrows left behind by prehistoric animals in South Africa. This latest study identified five distinct burrow sites and a separate fossil track site. The locations included:
The fossilized aardvark tracks were uncovered 3 kilometers east of Burrow Bay and 8 kilometers west of Drietfontein. These footprints exhibited the three-toed (tridactyl) structure characteristic of modern aardvarks, confirming their identity.
Determining which animal created these burrows was a complex process. The researchers compared the fossilized structures to modern burrows dug by different burrowing animals native to the region, including porcupines, bat-eared foxes, Cape foxes, springhares, honey badgers, and hyenas. However, each alternative was ruled out for various reasons:
Adding further confirmation, researchers discovered distinct claw marks inside two burrows, which matched the claw patterns of modern aardvarks. Dr. Charles W. Helm, the lead researcher of the study, stated, “Two of the burrows contained aardvark claw scratch marks, finding and identifying those provided a really meaningful moment.”
Since none of the burrow sites contained organic material suitable for direct radiocarbon dating, the team used a technique called Optically Stimulated Luminescence (OSL) dating, which measures the last time quartz grains in the surrounding rock were exposed to sunlight.
The analysis provided approximate ages for each burrow site:
These dates place the burrows firmly within the Pleistocene epoch, a period characterized by dramatic climatic shifts and significant megafaunal activity.
