Forgotten Tail Bone Identified as Antarctica's First Dinosaur Fossil
A fossil that spent forty years forgotten in a drawer in Cambridge has been identified as the first dinosaur bone ever found in Antarctica. The specimen was collected in nineteen eighty-five, but geologists originally believed it belonged to a marine reptile. Recently, Doctor Evans recognized its dinosaur-like features, and Professor Barrett confirmed it was a Titanosaur tail bone. This seven-meter-long plant eater lived eighty-two million years ago, when Antarctica was covered in lush forests rather than ice.
An unassuming fossil that stayed in a storage drawer for forty years is the first dinosaur bone discovered in Antarctica. The specimen was originally unearthed in 1985 on James Ross Island, but the team was uncertain about its identity. Consequently, they stored it in the British Antarctic Survey collections in Cambridge, where it remained completely unnoticed.
The breakthrough occurred when collections manager Dr. Mark Evans spotted the fossil while cataloguing thousands of polar specimens. He noticed that it resembled a dinosaur vertebra, which contrasted with the team's original theory that it belonged to a marine reptile. Dr. Mike Thomson sketched the ten-centimeter fossil in his notebook on 9 December 1985, describing it as a reptile vertebra.
To verify his theory, Evans contacted Professor Paul Barrett from the Natural History Museum. Barrett examined the fossil and confirmed that it was a tail bone belonging to a Titanosaur. This group contains the largest herbivorous dinosaurs that ever walked the Earth, with some species growing over thirty-five meters long.
Based on the size of this specific vertebra, the scientists estimated that this Antarctic dinosaur was approximately seven meters long. The biggest species weighed about sixty tonnes, whereas this animal was probably a juvenile or a small adult. This creature inhabited Antarctica eighty-two million years ago, when the region was covered in lush forests rather than ice.
The discovery is significant because the fossil record in Antarctica is very sparse due to the challenging ice cover. Barrett explained that the fossil shows how habitable this continent once was and helps scientists understand the ancient polar ecosystems.
