First dinosaur bone found in Antarctica identified after 40 years
A dinosaur bone discovered in Antarctica more than 40 years ago has finally been identified as a vertebra from a titanosaur, the largest creature ever to walk the Earth. The fossil is the first dinosaur bone ever found on the continent.
The fossil was collected during an expedition to Antarctica in 1985 and stored in the geology collection of the British Antarctic Survey in Cambridge. It was recorded in a field notebook by paleontologist Mike Thompson, who noted it as a 'vertebrate of large reptile' and made a detailed sketch. However, the bone remained unidentified for decades.
Dr Mark Evans of the British Antarctic Survey spotted the unassuming fossil while going through the collection. He recognised its distinctive shape, with a socket at one end and a ball at the other, a combination unique to titanosaurs. 'As soon as I saw it I knew what we were dealing with,' he said.
The vertebra comes from the tail area of a titanosaur. While the largest titanosaurs could reach up to 35 metres in length and weigh 60 tonnes, this particular dinosaur was much smaller, about 7 metres long. This suggests it may have been a young animal or a dwarf species.
The fossil dates to the late Cretaceous period, about 80 million years ago, when Antarctica was covered in lush forest and provided ample food for plant-eating titanosaurs. The discovery adds another piece to the puzzle of titanosaurs and the world they lived in.
More than 100 species of titanosaur have now been discovered, ranging from small animals about 5 or 6 metres long to giants up to 35 metres. All were plant eaters, walked on all fours, and had long necks and counterbalancing tails.
A full scale cast of a titanosaur, on loan from the Natural History Museum, is currently on display at Peterborough Cathedral.

Channel Perspectives
Editorial focus, emphasis angles, and key quotes from each reporting news station.
BBC News at One focused on the scientific significance of the discovery, the long delay in identification, and the details of the titanosaur. The tone was informative and slightly wonderstruck, highlighting the fossil's unassuming appearance and the detective work involved. It also included a visual demonstration of the vertebra's unique features and a comparison with a full scale cast.
- “It's only when you start thinking what's in this drawer and sometimes you come across something and you think this looks interesting”
- “Here we can see the socket of that joint at one end and the ball at the other end and this is a combination of features that's completely unique to these types of dinosaurs and as soon as I saw it I knew that's what we were dealing with”
- “We now know that they range in size from quite smallish animals only about 5 or 6 metres in length up to these huge giants that reach up to about 35 metres and also weighing up to 60 tonnes or more in weight”
