A fossil collected in Antarctica more than 40 years ago has turned out to be a rare dinosaur discovery.
The bone was found in 1985 during an expedition to Antarctica’s James Ross Island and was originally recorded as belonging to a large reptile.
Decades later, a paleontologist reviewing the British Antarctic Survey’s collections recognized that the fossil might be something more specific: a dinosaur bone.
Researchers confirmed that the bone came from the tail of a long-necked, plant-eating dinosaur called a titanosaur. Scientists have not yet identified the exact species.
The discovery is especially notable because dinosaur fossils are rare in Antarctica, where ice makes fieldwork difficult. Millions of years ago, though, the region was much warmer and covered in lush forests.
It is a reminder that discovery does not always happen in the field. Sometimes, progress comes from revisiting what has already been collected with fresh questions, better tools, and new expertise.
