Scientists have identified a fossil as the first dinosaur bone ever discovered in Antarctica [3].
The discovery provides the first direct evidence of dinosaurs on the frozen continent. This finding offers new insights into the prehistoric ecosystem of Antarctica and the global distribution of Titanosaurs [2, 5].
The specimen is a tail vertebra belonging to a Titanosaur [2]. It was originally collected during a British Antarctic Survey (BAS) expedition in 1985 [2, 4]. Following its excavation, the bone was stored within the BAS geology collection in Cambridge, United Kingdom [1, 2].
Despite being in the collection for decades, the fossil remained unidentified. It spent approximately 40 years in a drawer before researchers from the BAS and the University of Cambridge identified it in 2024 [1, 4].
The identification confirms that large dinosaurs once inhabited the region. Titanosaurs were among the largest land animals to ever exist, and this specimen serves as the first confirmed dinosaur bone from the continent [3].
The process of identifying the bone underscores the importance of revisiting existing museum collections. The specimen had been forgotten in storage since the mid-1980s, a gap of nearly four decades that delayed the confirmation of Antarctica's dinosaur history [1, 4].
“The discovery provides the first direct evidence of dinosaurs on Antarctica.”
This discovery shifts the understanding of prehistoric biodiversity in the Southern Hemisphere. By confirming the presence of Titanosaurs in Antarctica, scientists can better map the migration patterns and environmental conditions of the Cretaceous period, proving the continent was once a viable habitat for some of the largest creatures in Earth's history.
