The discovery of 200 million-year-old dinosaur bones in what is now South Africa has led to the identification of a 12-ton creature that walked on four legs and crouched like a cat. The giant plant eater was a sauropodomorph, a distant cousin of the long-necked sauropod (think Brontosaurus). But this creature was much larger and lived much earlier in the age of dinosaurs. Researchers named it Ledumahadi mafube, Southern Sotho for “giant thunderclap [at] dawn.” It took paleontologists 20 years to collect the giant bones and piece together this dino’s story.
