In a remarkable paleontological discovery, researchers from the Aragosaurus-IUCA at the University of Zaragoza have unearthed more than 30 dinosaur eggs in Huesca, Spain, which are estimated to be about 72 million years old, dating back to the Late Cretaceous period. This find brings Spain back into the spotlight of global paleontology, showing its historical significance in the study of dinosaurs.

The eggs were discovered in the Loarre area, where experts identified an extensive nesting site used by titanosaurids, which were large herbivorous dinosaurs that roamed the region shortly before the mass extinction event that wiped out the dinosaurs. The nest site has been known since 2019, but it has garnered renewed international attention as recent analyses conducted between 2025 and 2026 confirmed the existence of these eggs and highlighted the site's importance.

The condition of the eggs has amazed scientists, as many are found intact with well-preserved shells. This level of preservation provides unique insights into the reproductive behaviors and biology of these ancient creatures, contributing significant knowledge to the scientific community regarding the final stages of the dinosaurs' existence. The find emphasizes the richness of Spain's paleontological heritage and the ongoing importance of archaeological research in the region.
