Southern Africa dinosaur tracks rewrite history

A hidden map of the ancient world

Imagine standing on the rugged coastline of South Africa's Western Cape, where the salt spray of the Indian Ocean meets the weathered cliffs. For decades, geologists believed this landscape held little promise for Cretaceous life, as the fossil record of southern Africa went abruptly quiet following the volcanic eruptions that smothered the region nearly 182 million years ago. But today, the rocks have told a different story. In a breathtaking discovery near Knysna, scientists have identified more than two dozen dinosaur tracks preserved in the Brenton Formation, dating back approximately 132 million years. These aren't just footprints; they are time capsules that rewrite the history of an entire continent.

For many decades, the prevailing scientific narrative held that the great Gondwana break-up - and the massive Karoo lava flows that accompanied it around 182 million years ago - had effectively ended the dinosaur record in southern Africa. The inland Karoo Basin, where most of the region's dinosaurs once roamed, fell silent in the fossil record for the entire Jurassic Period. However, these newly identified tracks prove that life didn't just survive; it thrived. Dinosaurs were still roaming these coastal plains some 50 million years after that volcanic cataclysm. It is as if we found a lost chapter of a book we thought we had finished reading.

The footprints of the giants

What makes this discovery so magical is the sheer variety of the tracks. The research team, led by Charles Helm, a research associate at the African Centre for Coastal Palaeoscience at Nelson Mandela University, has carefully documented prints that are interpreted to include theropods, possibly ornithopods, and possibly sauropods. These tracks were formed in a delicate dance of nature: dinosaurs walked across moist sediment - perhaps tidal channels or river beaches - and those prints were then baked dry by the sun before being buried under layers of sand and silt. Over millions of years, that mud turned to stone, preserving the fleeting moments of a prehistoric afternoon.

Walking along these sites feels like walking through an ancient corridor. You can see the distinct prints of bipedal theropods and possibly ornithopods, their three-toed marks leaving sharp indentations that hint at a purposeful gait. Nearby, larger impressions suggest the possible presence of long-necked sauropods, telling a story of a slower, heavier pace. These tracks provide a behavioural snapshot that skeletal fossils simply cannot. While a bone tells us what an animal looked like, a footprint tells us how it moved, how fast it travelled, and whether it was alone or part of a bustling Cretaceous community.

Challenging the volcanic narrative

To understand why this is so significant, we have to look back at the Earth's fiery past. About 182 million years ago, the region was smothered by the Drakensberg lavas - a series of massive volcanic flood basalt eruptions that altered the global climate and buried much of southern Africa's interior under lava. For a long time, the lack of fossils above these volcanic rocks led researchers to believe that the region's dinosaur record had come to an abrupt, permanent end. The silence in the fossil record throughout the Jurassic was a gap that many assumed was absolute.

This discovery shatters that silence. By dating the Knysna tracks to approximately 132 million years ago, researchers have bridged a massive temporal gap. These are now the youngest dinosaur tracks ever recorded in southern Africa - some 50 million years younger than the previous record-holders found in the inland Karoo Basin. It proves that despite the volcanic cataclysms, the resilience of life in southern Africa was extraordinary. The dinosaurs didn't flee or vanish; they adapted to the changing geography as the supercontinent of Gondwana began to splinter apart. The coastal margins of what is now the Western Cape became a sanctuary, a fertile strip of land where life could persist against the odds.

A new frontier for South African paleontology

This find opens up a world of wonder for future explorers. If these tracks exist, what other secrets are hidden in the cliffs and intertidal zones of the Garden Route? The discovery highlights the importance of ichnology - the study of trace fossils. While traditional palaeontology often focuses on the hunt for bones, ichnology looks at the impressions left behind. In many ways, these tracks are more intimate. They are the direct evidence of a living, breathing creature's interaction with its environment.

The Knysna tracks are, in fact, only the second record of dinosaur tracks from the Western Cape Province, following a discovery of 140-million-year-old tracks reported from the nearby Robberg Formation in 2025. Together, these finds suggest that the region's Cretaceous fossil record is far richer than previously thought, and that further systematic exploration of suitable rock formations along the coast is now well warranted. It is a reminder that our planet is always hiding more than it reveals. Beneath our feet, even in places we think we know well, there are still giants waiting to be discovered, inviting us to marvel at the enduring rhythm of life across the deep stretches of time.
