It is about a metre high, weighs 30kg, has a long tail and a rather small head. The animal, whose skeleton has just been discovered in Zimbabwe by an international team of palaeontologists, could be mistaken for an ordinary lizard.
However, even though it is smaller than the giant long-necked dinosaurs that were to be its descendants, Mbiresaurus raathi is indeed a creature that dates back to that distant era when the very first mammals appeared. It ran on two legs, about 230 million years ago.

Although the skeleton – almost complete, which is rare – was found during expeditions in 2017 and 2019, the team of researchers from Zimbabwe, Zambia and the US only published their results in the prestigious scientific journal Nature on 31 August.

Belonging to the sauropodomorph species, the “Rhodesian” dinosaur is presented as the oldest known dinosaur fossil on the continent. The animal was probably an omnivore that fed on plants, small animals and insects.

Just out, Africa’s oldest dinosaurs! Paper and project led by Chris Griffin and an international team of Zimbabwean, American, Zambian, and Brazilian scientists.

Its name, ‘Mbiresaurus raathi’, is a double tribute to the Mbire district of northeastern Zimbabwe – where the skeleton was found – and to palaeontologist Michael Raath, the first researcher to report fossils from that part of the world. The discovered specimen has joined others at the Natural History Museum in Bulawayo, Zimbabwe.
Yale University scientist Christopher Griffin unearthed the first bone from this skeleton, a femur. He began digging in Zimbabwe based on the theory that all the present continents once formed a single landmass called Pangea. He calculated that ancient Zimbabwe was likely to have been positioned at the same latitude as modern South America at that time. Furthermore, dinosaur remains from the same period and with the same characteristics as Mbiresaurus raathi were found in Brazil and Argentina.
Human migration would have been much simpler during the supercontinent era, when Africa, South America and Europe were joined. But today’s man, had he been present, would certainly have invented a wall…
Understand Africa's tomorrow... today
We believe that Africa is poorly represented, and badly under-estimated. Beyond the vast opportunity manifest in African markets, we highlight people who make a difference; leaders turning the tide, youth driving change, and an indefatigable business community. That is what we believe will change the continent, and that is what we report on. With hard-hitting investigations, innovative analysis and deep dives into countries and sectors, The Africa Report delivers the insight you need.
