150-million-year-old dinosaur eggs discovered in Portugal on March 9, 2026

Key facts

• A nest containing 10 intact dinosaur eggs from the Upper Jurassic era was discovered at Santa Cruz Beach in Torres Vedras, Portugal.
• The discovery was made by Carlos Natário, a researcher at the Centre for Research in Paleobiology and Paleoecology (Ci2Paleo) under the Torres Vedras Natural History Society (SHN).
• Preliminary studies suggest the eggs, measuring 5 centimetres in diameter, belong to a carnivorous theropod, which was a two-legged predator of the Jurassic era.
• Researchers at the SHN laboratory are using Computed Tomography (CT) scans to perform a virtual excavation and create high-resolution 3D models of the egg interiors.
• The eggs were found in granular sandstone, indicating they were laid on a riverbank and fossilised at the original location without being moved by ancient floods.
