Europe's DOG-SIZED Triceratops Cousins Hid in Museum Drawers for 100 Years

Every now and then, a single new fossil completely recontextualizes a whole group of dinosaurs that paleontologists thought they had figured out. The Western European Mesozoic record is full of those moments. Fragmentary fossils, broken bones, and isolated scraps have led generations of scientists to conclusions that new discoveries keep overturning — but in the weirdest twist, some of those wrong conclusions turn out to be accidentally right, just for completely different reasons. Topics covered: • The Iguanodon wastebasket and 200 years of misclassification • Franz Nopcsa and the discovery of insular dwarfism • The Rhabdodontidae: Mochlodon, Zalmoxes, Rhabdodon • Ajkaceratops kozmai and the 2026 Nature paper by Maidment et al. • The new CT-reconstructed skull and what it reveals • How these animals fit into the global ceratopsian family tree • What European ceratopsians mean for dinosaur biogeography 📺 Were ceratopsians more omnivorous than we think?
