A Famous Dinosaur Finally Left North America. It Took 150 Million Years.

Giant Diplodocus, known for its whip-like tail, was thought exclusive to the US. But 145-million-year-old remains just unearthed in Spain are rewriting its Jurassic history.

For millions of years, the Diplodocus — that iconic, long-necked, whip-tailed gentle giant — seemed like a proudly American dinosaur. Every single confirmed fossil of this particular long-necked plant-eater, which roamed the Earth roughly 155 to 145 million years ago, was found exclusively in the western United States.

Apparently, someone forgot to tell a Diplodocus in Spain.

The OG Globetrotter

Paleontologists have just announced the first-ever Diplodocus remains found outside of North America, unearthed in El Castellar, a charming little town in Teruel, Spain. Imagine being the paleontologist who unearths that. "Wait a minute... you're not supposed to be here."

The discovery includes 14 remarkably preserved tail bones, plus several chevron bones from the tail, which are exactly what you want to find when you're trying to identify an ancient creature. Researchers put these bones through the wringer, comparing them to known Diplodocus anatomy and using advanced evolutionary analyses. The verdict? Definitely a Diplodocus, and a close relative of the Diplodocus hallorum, no less.

Sergio Sánchez Fenollosa, the lead author and a graduate student at the Joint Paleontology Foundation Teruel-Dinópolis, confirmed that all the evidence consistently pointed to one conclusion: This guy was a Diplodocus.

This particular Spanish sauropod lived about 150 million years ago. Its existence suggests that during the Late Jurassic period, dinosaurs were doing a bit of international travel, likely utilizing temporary land bridges that popped up in the fledgling North Atlantic Ocean. Back then, the supercontinent Pangea was in the middle of a rather dramatic breakup, and the Atlantic was just starting to get its act together.

At about 82 feet long, this Spanish Diplodocus was just as massive as its North American cousins, which, if you think about it, is both impressive and slightly terrifying. Its remains are now proudly on display at the Aragones Museum of Paleontology at Dinópolis. So, next time you're in Spain, you can pay your respects to the dinosaur who broke all the rules.

Brightcast Impact Score (BIS)

This article celebrates a significant scientific discovery: the first Diplodocus fossils found outside the United States, indicating dinosaur migration between continents. The evidence is strong, based on anatomical comparisons and phylogenetic analyses published in a scientific journal. While the direct impact on current beneficiaries is limited, the discovery significantly advances paleontological understanding.
