In brief
In 1985 a bone collected on James Ross Island was stored away in a masonry drawer at the British Antarctic Survey. Forty years later paleontologists recognised it as a Titanosaur tail vertebra, the first dinosaur fossil recorded from Antarctica. The discovery provides insight into the distribution and ecology of large herbivorous dinosaurs during the Late Cretaceous, when the continent was covered in lush forest. It also highlights the challenges of unearthing fossils beneath the ice-covered landscape. The find was published in a scientific journal and could pave the way for further exploration of Antarctica’s fossil record.
A bone that sat forgotten in a drawer for 40 years is now the first dinosaur fossil ever found in Antarctica. The specimen, a Titanosaur tail vertebra, was collected in 1985 on James Ross Island but only recognised as dinosaurian when Dr Mark Evans discovered it among thousands of specimens at the British Antarctic Survey’s geology collections in Cambridge.
Paleontologists confirmed its identity by comparing its distinctive hollow and protrusions to known Titanosaur vertebrae. Titanosaurs were large, plant‑eating dinosaurs with long necks and tails that grew primarily in the Southern Hemisphere. This particular bone hints that a 7‑metre-long Titanosaur roamed the continent 82 million years ago, when Antarctica was covered in forests rather than ice.
The find underscores how much of the continent’s prehistoric life remains hidden beneath its ice. It also demonstrates the value of reassessing archived collections—what once was deemed a vague marine reptile (or a “large reptile” in a field notebook) can become a landmark in science. Further research is already underway to explore the region more thoroughly.
