Hungarian researchers solve one of the most important mysteries surrounding European herbivorous dinosaurs

A research group led by Hungarian geologist and paleontologist Attila Ősi has significantly altered the understanding of Eurasian dinosaurs, demonstrating the presence of collared and horned dinosaurs in Late Cretaceous Europe using fossils from Hungary's Bakony Hills. Their findings, published in Nature, confirm the existence of ceratopsians in Europe, previously thought to be limited to Asia and North America. The team has identified Ajkaceratops kozmai and linked it to Mochlodon vorosi, suggesting a misclassification of some species in Europe. The research highlights the diversity of ceratopsians in the region and calls for a re-evaluation of historical fossil collections.
