Researchers recently announced a discovery that changes the scientific understanding of presence of horned dinosaurs in Europe: A more complete fossil of a ceratopsian dinosaur found in western Hungary provides the clearest evidence to date that these animals – a group famous for specimens like the Triceratops – were not restricted to Asia and North America, as previously believed.
The fossil belongs to the genus Ajkaceratops kozmai, a herbivorous dinosaur from the period Upper Cretaceous who lived about 84-85 million years ago in prehistoric Europe, when much of the continent consisted of an archipelago of islands off the ancient sea of Tethys.The piece was studied by an international team of paleontologists who compared the new cranial evidence – obtained using advanced imaging techniques – with fossils of ceratopsian dinosaurs known from other parts of the world.
Before this analysis,european ceratopsians were only suspected based on fragmentary fossils and their presence was disputed due to the few remains found.The new study, published in the journal Nature, showed that anatomical features of the skull – such as the shape of the beak and internal bone structure – are consistent with the group of ceratopsians, confirming with confidence that these “horned dinosaurs” indeed lived on the European continent during the Cretaceous.
This confirmation forced scientists to reevaluate ancient European dinosaur fossils that could have been wrongly classified as belonging to other groups.In some cases,specimens previously attributed to different linages were reinterpreted as possible ceratopsians,suggesting that this group may have been more diverse and widespread in europe than previously imagined.
the impact of this discovery goes beyond the simple presence of a new type of dinosaur in Europe. It challenges the traditional model of paleobiogeography – which believed that ceratopsians spread only between Asia and North America – and suggests that these herbivores with beaks and horns crossed ancient Cretaceous seas and islands, probably taking advantage of dispersal routes that connected different land belts.
