Newly Discovered Dinosaur Species Shocks Scientists
Researchers studying a fossil in South Africa have discovered what they believe to be a previously unknown species of dinosaur dating back almost 200 million years. The fossil, originally thought to be the arm of a larger dinosaur, is now believed to belong to a relative of titanosaurs. The discovery indicates that these types of dinosaurs could live to be much smaller as adults. The fossil weighs 70 kilograms, and researchers hope to find a more complete individual from which they can name the new species.
