Diplodocus, Long Thought Exclusively American, Turns Up in Spain
summary
Paleontologists have discovered the first confirmed fossils of the Diplodocus genus outside of North America, found in the Teruel province of Spain. This discovery proves that these same giant sauropods lived in Europe during the Late Jurassic period. The find suggests that dinosaurs migrated between North America and Europe via temporary land bridges. This changes the understanding of dinosaur distribution and the faunal exchange between continents.
key points
- Researchers identified 14 tail vertebrae and several chevron bones from a specimen approximately 25 meters long, matching the size of its American relatives.
- The discovery provides strong evidence for intercontinental dispersal of dinosaurs, indicating that the proto-North Atlantic Ocean periodically receded to allow travel between continents.
- The fossils were unearthed at the La Tejería site, establishing Teruel as a key location for studying the diversity of Jurassic sauropods.

discussion positive
consensus
Commenters generally agree that the discovery of Diplodocus fossils in Spain suggests a prehistoric land bridge existed between North America and Europe. While some users debate the semantics of the term 'American' and engage in political banter regarding US-Europe relations, the core scientific interest centers on the mobility of dinosaurs during the Late Jurassic. The sentiment is largely curious and appreciative of thepangeamap.com tool for visualizing these ancient movements.
top insight
The discovery highlights how limited our understanding of dinosaur biodiversity is, as our current knowledge relies on a few specific geological sites that were conducive to fossilization. Most species likely evolved and went extinct without leaving any identifiable fossils, meaning the fossils we find are merely snapshots of a much larger, more complex biological history.
