Sterkfontein Caves Research

Happy Tuesday!

Today we'd like to congratulate Dr Matthew Caruana on his latest co-authored publication!

The article, "Swartkrans Paranthropus and Sterkfontein Australopithecus from southern Africa had different locomotor repertoires", details a comparative examination of the internal bone anatomy of a recently described c. 1.8 Ma P. robustus articulating femur and tibia, which suggests distinct patterns of joint loading and locomotor behavior.

The analysis of cortical bone in the hip and trabecular bone in the ankle, knee, and hip joints suggests that P. robustus habitually adopted a high frequency of ankle, knee, and hip flexion, as required for climbing, while Australopithecus from a c. 3.4 Ma level at the site of Sterkfontein displays a more modern human-like structural pattern across the lower limb joints consistent with comparatively more frequent terrestrial bipedalism.

These results reveal that geologically younger P. robustus likely used arboreality more frequently than older Sterkfontein Australopithecus.

We are pleased to welcome Recognise Sambo as the new Education & Exhibits Manager at Sterkfontein Caves.

Recognise joins the team with a strong background in palaeoanthropological research and public engagement within the Cradle of Humankind. We look forward to her contribution to the development of educational initiatives, exhibitions, and science communication at one of South Africa’s most important fossil heritage sites.

Please join us in welcoming her to the team.

Wits Sterkfontein Caves research has once again featured prominently across recent Faculty of Science communications, highlighting both major scientific discoveries and the people behind them.

Recent features included the virtual reconstruction of the iconic Australopithecus fossil “Little Foot,” offering new insight into early hominin facial evolution; groundbreaking nitrogen isotope research showing that *Australopithecus* at Sterkfontein consumed little to no mammalian meat; recognition of this work as one of the Smithsonian’s Top Human Evolution Discoveries of 2025; and a tribute recognising the invaluable contributions of Sterkfontein Caves technicians, whose expertise has been central to excavation, fossil preparation, and interpretation over decades of research.

Together, these stories reinforce the global significance of research from the Sterkfontein Caves and its continued role in advancing palaeoanthropology at the University of the Witwatersrand.

🚨 New Publication Alert! 🚨

A new study by Ronald Clarke and Travis Pickering, published in the Transactions of the Royal Society of South Africa, revisits one of South Africa's most famous fossil discoveries, a lower jaw known as SK 15 from Swartkrans Cave.

Some researchers recently argued that SK 15 belonged to a robust human relative called Paranthropus. However, Clarke and Pickering disagree. They argue that the fossil does not show the key features expected in Paranthropus and may instead belong to an early member of our own genus, Homo, or a late-surviving Australopithecus.

Why does this matter? Because identifying which species a fossil belongs to helps scientists understand how many different human relatives lived in South Africa nearly 2 million years ago and how they may have interacted with one another.

🚨 New Publication Alert!🚨
New research by Cazenave et al. (2026), published in the Proceedings of the National Academy of Sciences (PNAS), examining fossil leg bones (femora and tibiae) from Sterkfontein and Swartkrans suggests that early southern African hominins did not all move in the same way.

By analysing the internal structure of the bones, researchers found that Paranthropus robustus likely retained more climbing-related behaviours, while Sterkfontein Australopithecus shows evidence of more frequent upright walking on the ground.

The findings add to growing evidence that different hominin species occupied distinct ecological niches within the Cradle of Humankind millions of years ago, highlighting the diversity and complexity of early human evolution.

🚨 New Article Alert!🚨
As we approach the 90th anniversary of the discovery of TM 1511 this August, we are pleased to share this newly published feature article by Ron Clarke and Lazarus Kgasi on the DITSONG: Museum of Natural History website.

Discovered at Sterkfontein Caves in 1936 by Dr Robert Broom, TM 1511 was the first adult Australopithecus cranium ever found and became a landmark discovery in the history of palaeoanthropology. The article reflects on the fossil’s discovery, scientific importance, and lasting contribution to our understanding of human evolution and the Cradle of Humankind.

A remarkable milestone celebrating 90 years of one of South Africa’s most important fossil discoveries. Stay tuned for more as we approach this important anniversary later this year.

🚨 New Feature Alert! 🚨
Proud to see Sterkfontein fossil technician Abel Molepolle featured in the the Sunday Times for his extraordinary contribution to South African palaeoscience. From being born at Sterkfontein to spending decades preserving its fossils, his story is inseparable from the history of the Cradle of Humankind itself.

Abel played a vital role in the recovery and preservation of “Little Foot”—one of the most remarkable Australopithecus skeletons ever discovered—dedicating years of patient and meticulous work to excavating, cleaning, moulding, and casting the fossils.

He’s now retired, but his legacy endures. A true legend whose work now reaches museums and research institutions across the world.

Wishing him a well-deserved retirement and celebrating an incredible legacy.

Realeboga Ntate Kgame!
