First Antarctic Dinosaur Bone Discovered

Scientists have identified the first dinosaur fossil ever discovered in Antarctica after a specimen spent four decades forgotten in a drawer at the British Antarctic Survey in Cambridge.

The fossil, unearthed on James Ross Island in 1985, was initially catalogued as the remains of a large reptile before being stored among thousands of geological samples. Researchers have now confirmed it is a tail vertebra from a Titanosaur, a group of long-necked herbivorous dinosaurs that included some of the largest animals ever to roam Earth.

Experts from the British Antarctic Survey and the Natural History Museum said the fossil's distinctive ball-and-socket structure is unique to titanosaurs. Based on its size, scientists estimate the dinosaur measured around seven metres in length.

The animal is believed to have lived about 82 million years ago during the Late Cretaceous period, when Antarctica was covered by forests and had a much warmer climate capable of sustaining large plant-eating dinosaurs.

Researchers said the find is significant because dinosaur fossils remain exceptionally rare in Antarctica, where extensive ice cover conceals much of the prehistoric record. The rediscovered specimen provides new insight into ancient ecosystems that once thrived at the southernmost reaches of the planet.
