Scientists have confirmed the first Diplodocus fossil ever found outside North America, discovered in Spain. The 150-million-year-old sauropod, a type of long-necked, plant-eating dinosaur, measured about 25 meters (82 feet) in length. The fossils, including 14 well-preserved tail vertebrae and several chevron bones, were found at the La Tejería site in El Castellar, Teruel, Spain. The discovery was made by researchers from the Fundación Conjunto Paleontológico de Teruel-Dinópolis and published in the Journal of Vertebrate Paleontology, a respected scientific journal. Previously, all confirmed Diplodocus fossils had been found in the Morrison Formation in the western United States. The Spanish specimen is also among the most complete diplodocid skeletons ever discovered in Europe. The study's lead author, Sergio Sánchez Fenollosa, a PhD student in biodiversity and evolutionary biology at Fundación Dinópolis, noted that the anatomical features of the fossils matched those of Diplodocus species. Evolutionary analyses confirmed the identification, providing strong evidence that this dinosaur once roamed Europe. The presence of Diplodocus in Spain suggests that dinosaurs could move between North America and Europe during the Late Jurassic period. Researchers believe this migration may have occurred through temporary land bridges created when sea levels dropped, exposing parts of the proto-North Atlantic Ocean. This discovery supports the idea of faunal exchange between continents, showing that species could travel across regions that are now separated by oceans. The Spanish Diplodocus was about the same size as its North American relatives and joins other large sauropods found in the region, such as Turiasaurus and Losillasaurus. The fossils are now on display at the Museo Aragonés de Paleontología at Dinópolis in Teruel, Spain. The excellent preservation of the bones allowed scientists to identify key anatomical features, such as large air pockets in the vertebrae and distinctive forked chevron bones. These traits are typical of Diplodocus and helped confirm the identification using both traditional methods and advanced phylogenetic analysis. Diplodocus is one of the most recognizable dinosaurs, known for its massive size, long whip-like tail, and small head. It was first discovered in the United States in 1878 and has since become a symbol of paleontology, featured in major museums worldwide. The Spanish discovery adds to the growing understanding of the diverse dinosaur ecosystems that existed in Jurassic Iberia, which included not only sauropods like Diplodocus but also theropods, stegosaurs, and ornithopods.
