A fossil cataloged as a marine reptile in 1985 has been re-examined and identified as a 6-meter titanosaur, a land-dwelling dinosaur. This reclassification provides new evidence about terrestrial ecosystems in Antarctica during the Cretaceous, challenging prior assumptions about the continent's prehistoric biodiversity. The finding is based on morphological reanalysis, though the original specimen's fragmentary nature may limit certainty.
