Scientists have stumbled on a rare dinosaur fossil from Antarctica tucked in a drawer. It comes from the tail of a long-necked, plant-eating dinosaur called a titanosaur. The fossil was discovered in 1985 during an expedition meant to map the area’s rock layers, and was recorded as belonging to a large reptile. Decades later, scientists have analyzed the bone and confirmed it was a dinosaur. Dinosaur fossils are rare to find in Antarctica because of the unforgiving ice caps. The findings were published Monday in the journal Acta Palaeontologica Polonica.
