Stunning 150-million-year-old stegosaur skull rewrites dinosaur evolution

Paleontologists from the Fundación Conjunto Paleontológico de Teruel-Dinópolis have published new findings in the scientific journal Vertebrate Zoology describing an extraordinary stegosaur skull discovered in Riodeva (Teruel, Spain). The fossil, which comes from a plated dinosaur that lived about 150 million years ago, is also helping researchers propose a new explanation for how stegosaurs evolved and spread across the world.
