First Diplodocus Found in Europe Redefines Jurassic Distribution

Paleontologists have unveiled the first evidence of a Diplodocus outside its previously established North American territory, a significant finding that reshapes our understanding of this dinosaur's geographical range during the Late Jurassic epoch.

Researchers from the Fundación Conjunto Paleontológico de Teruel-Dinópolis detailed the remarkable discovery in the Journal of Vertebrate Paleontology. This specimen is among the most complete diplodocid skeletons unearthed in Europe, particularly noted for its well-preserved bones.

The fossil, uncovered at the La Tejería site in El Castellar, Teruel, Spain, includes 14 tail vertebrae and several chevron bones, found by a dedicated team from the Fundación Dinópolis.

Prior to this dig, the only recognized Diplodocus specimens were sourced from the Morrison Formation in the western United States, making this European find particularly notable.

According to Sergio Sánchez Fenollosa, a PhD student specializing in biodiversity and evolutionary biology and the lead author of the study, enthusiasm about the find was palpable. "We could see the pieces of the puzzle coming together," he remarked. "Initial observations of the osteological features revealed striking similarities with several diplodocine sauropods, leading us to identify a series of characteristics typical of Diplodocus species."

As they advanced through various evolutionary analyses, the evidence solidified, leading the team to confidently classify the specimen as a Diplodocus. The research points to compelling paleontological evidence indicating significant exchanges of dinosaur populations across the proto-Atlantic during the Late Jurassic, enhancing our grasp of the Mesozoic ecosystems in the Iberian Peninsula.

This Diplodocus lived approximately 150 million years ago, at a time when dinosaurs could traverse land bridges that formed due to falling sea levels in the early North Atlantic, suggesting that species migration between North America and Europe was plausible.

This discovery enriches our understanding not only of Diplodocus's habitat but also of the broader context of dinosaur migration and adaptation.

Co-author Dr. Alberto Cobos, the managing director of Fundación Dinópolis, highlighted the size of the new specimen, estimating it to be around 25 meters long, comparable to its North American relatives. It joins other significant sauropods, like Turiasaurus and Losillasaurus, highlighting the diverse dinosaur lineage present within the Spanish Jurassic period.

The exceptional preservation of these fossils allowed the research team to examine distinguishing anatomical traits linked to Diplodocus. They employed traditional anatomical comparisons alongside advanced phylogenetic analysis methods, confirming its classification within the Diplodocus genus and identifying it as closely related to Diplodocus hallorum.

This Diplodocus specimen has been displayed for both ongoing research and educational purposes at the Museo Aragonés de Paleontología located in Teruel, positioning the city as a focal point for paleontological studies.

Diplodocus itself stands as one of the most recognizable dinosaurs, celebrated for its impressive length, long tail, and relatively small head. Since its initial discovery in the U.S. in 1878, casts of its skeleton have been prominent features in natural history museums globally, contributing to its status as an iconic paleontological symbol.

The Spanish discovery not only provides a new geographical point for Diplodocus but also serves as a window into the remarkable diversity of dinosaurs that once inhabited eastern Iberia during the Late Jurassic. The fossil site has yielded remains from various dinosaur groups such as sauropods, theropods, stegosaurs, and ornithopods, indicative of a complex and rich dinosaur ecosystem thriving in ancient coastal habitats.
