A nearly complete stegosaur skull from Spain, attributed to Dacentrurus armatus, reveals skull features that define a new Neostegosauria lineage and forces a major revision of stegosaur evolution, suggesting this group ranged across Africa, Europe, North America, and Asia from the Middle Jurassic to Early Cretaceous.
Paleontologists in Teruel, Spain uncovered the most complete stegosaur skull in Europe, dating to the Late Jurassic and attributed to Dacentrurus armatus. The fossil, found at the Están de Colón site in Riodeva, preserves key skull bones and a neck vertebra, offering unprecedented insight into stegosaur anatomy, feeding, and evolution. The discovery supports a new evolutionary grouping, Neostegosauria, and the site has yielded hundreds of fossils across growth stages, reshaping understanding of dinosaur diversity in the region.
A rare 150-million-year-old stegosaur skull found in Spain has led to the identification of a new dinosaur group called Neostegosauria, reshaping our understanding of stegosaur evolution and their geographic distribution during the Jurassic period.
