Researchers have identified Antarctica’s first known dinosaur fossil as belonging to a titanosaur, after the bone sat in a museum collection for decades. The fossil was collected during an expedition in 1985, and it was later stored in a drawer rather than studied in detail for about 40 years. Multiple outlets report that the specimen is part of the dinosaur’s tail, described as a rare find from Antarctica. Once re-examined, scientists concluded the remains fit within Titanosauridae, a group of very large sauropod dinosaurs.
The reports describe the discovery as the first dinosaur fossil found on Antarctica, providing evidence that dinosaurs lived on the continent when it had a very different climate and environment than today. One outlet also notes an estimate for the individual size, describing it as smaller than other members of the group, though the exact dimensions vary by account. The identification is presented as based on scientific analysis following the fossil’s rediscovery from storage, with researchers highlighting the significance of the specimen for understanding Antarctica’s prehistoric fauna.
