Decades in a drawer: Antarctica's first dinosaur fossil identified

The bone, originally collected by geologist Mike Thomson, languished within the British Antarctic Survey’s geology collection until Evans re-examined the fragment. By comparing the dimensions and structure against more complete fossil records, researchers confirmed it belonged to a titanosaur—a long-necked, herbivorous dinosaur. Published in Acta Palaeontologica Polonica, the study suggests this specific creature measured roughly 23 feet in length, a relatively modest size for its group, and likely died young. The remains appear to have drifted from the coast, sinking to the seafloor where they were preserved in marine rock.

While Antarctica once hosted lush forests, extreme ice conditions make the recovery of such specimens exceptionally rare. Thomson, who passed away in 2020, never lived to see the true nature of his discovery verified by modern analysis. Evans noted that the geologist would have been fascinated to learn the bone’s actual origin, marking a significant milestone in polar paleontology.
