Dinosaurs once flourished in Europe but when an asteroid hit 66 million years ago, they died quickly, according to a new study.
That an asteroid killed off the dinosaurs is widely held, but until recently dinosaur fossils from the late Cretaceous, the final period of dinosaur evolution, were almost exclusively found in North America. This raised questions about whether the sudden decline of dinosaurs in the American and Canadian west was merely a local story.
The new study synthesizes research on European dinosaurs over the past two decades. Fossils of late Cretaceous dinosaurs are now commonly discovered in Spain, France, Romania, and other countries.
