Steve Edwards was scanning the red rock along the shore of Lake Kariba in northern Zimbabwe when he spotted something extraordinary—not a living animal, but the fossilized bones of one that walked the Earth 210 million years ago. This chance discovery would lead to the identification of a new dinosaur species, Musango matusadonaensis, a plant-eating dinosaur that stood on two legs, stretched 4.5 meters long, and weighed as much as a small horse.
Africa is home to up to 25% of the planet’s animal and plant species, and its deep evolutionary history runs even deeper than we thought. While South Africa has long been the center of attention for early dinosaur research, Zimbabwe’s fossils are now revealing a different story. For decades, scientists assumed that dinosaurs in this region were just the same species found across the border. But Musango, along with another recently discovered relative called Musankwa, shows that Zimbabwe had its own unique dinosaur communities during the Late Triassic period.
The fossils were found in brick-red mudstone and sandstone along the Nyamasango River near Musango Island—namesake of the new species. The area was once a dry landscape dotted with conifer trees and green river corridors, very different from today’s Lake Kariba, a massive artificial reservoir. Because the dinosaur’s skull didn’t survive, scientists can’t say for sure what it ate, but its close relatives were herbivores, so it likely munched on ancient plants too. Bone growth rings show this particular Musango was still growing when it died—just a teenager in dinosaur years.
The discovery was made possible by a team of international scientists led by Jonah Choiniere from the University of the Witwatersrand, working with researchers from Zimbabwe and the U.K. With sites deep inside Matusadona National Park, the team used a houseboat on Lake Kariba as a floating lab and home base during two expeditions in 2017 and 2018. Since then, they’ve been carefully cleaning and studying the fossils, uncovering clues about how life evolved in southern Africa.
What makes this find so exciting is that it challenges old assumptions. These dinosaurs aren’t just copies of South African species—they’re distinct, suggesting that regional environments shaped evolution in surprising ways. Scientists now believe that differences in climate, vegetation, or geography may have driven these unique adaptations.
As more fossils emerge from Zimbabwe’s ancient rocks, we’re learning that the story of dinosaurs is far more diverse than we once believed—and it’s still being written.
