The Jurassic and Cretaceous periods were the golden age of dinosaurs, during which the prehistoric giants roamed the Earth for nearly 135 million years. Paleontologists have unearthed numerous fossils from these periods, suggesting that dinosaurs were abundant throughout the world. But where and when dinosaurs first came into existence has been difficult to ascertain.

Researchers from the Complutense University of Madrid and the Universitat Autònoma de Barcelona identified in Lleida a series of dinosaur eggs with a unique characteristic: they are oval in shape. The discovery represents proof in favour of the hypothesis that birds and non avian theropods, dinosaurs from the Cretaceous Period, could have a common ancestor.
