Scientists have identified the first dinosaur bone ever collected from Antarctica, a tail fragment belonging to a long-necked, plant-eating titanosaur. The fossil had been tucked away in storage for decades at the British Antarctic Survey before being recognized as significant.
Key Takeaways
Scientists have identified the first dinosaur bone ever collected in Antarctica, a tail fragment from a titanosaur discovered decades ago but only recently recognized. The fossil was found during an expedition to James Ross Island in 1985 and initially misidentified as a marine reptile.
- First dinosaur bone from Antarctica identified as titanosaur tail fragment
- Fossil collected in 1985, rediscovered in British Antarctic Survey collections
- Small for its species at about 23 feet long, possibly immature or small-bodied form
- Discovery published in Acta Palaeontologica Polonica journal
- Antarctica's climate millions of years ago was lush and temperate

The bone was originally discovered during an expedition to James Ross Island in 1985 by geologist Mike Thomson, who initially recorded it as a large reptile fossil. It wasn't until recently that paleontologist Mark Evans noticed the specimen while reviewing collections and suspected it might be something more extraordinary.
After analyzing the shape of the bone and comparing it to other dinosaur remains, researchers confirmed their discovery. The findings were published on Monday in the journal Acta Palaeontologica Polonica. At about 23 feet long, this particular titanosaur was small for its species and may have been young when it died.
The discovery is particularly significant because dinosaur fossils are rare in Antarctica due to the continent's harsh conditions. However, millions of years ago when this dinosaur lived, Antarctica would have been covered in lush temperate forests, providing ample food for large herbivores like titanosaurs.
