Researchers Identify 40-Year-Old Fossil as Antarctica's First Dinosaur Bone

3 articles · Updated · The Daily Beast · Jun 29

A fossil collected in 1985 on James Ross Island has been confirmed as Antarctica’s first known dinosaur bone after spending about 40 years forgotten in a Cambridge drawer.
Dr. Mark Evans of the British Antarctic Survey spotted the specimen’s distinctive structure while reviewing archived material, and Natural History Museum paleontologists then identified it as a Titanosaur tail vertebra.
Scientists estimate the animal was about 23 feet long and lived roughly 82 million years ago, likely as a juvenile or unusually small adult.
The find adds to evidence that Antarctica was once far warmer and forested, supporting diverse Late Cretaceous ecosystems unlike the ice-covered continent seen today.

Overview

In 2024, scientists confirmed Antarctica's first definitive dinosaur bone—a titanosaurian caudal vertebra—from James Ross Island, dating to the Cretaceous Campanian period. This bone, found in the Santa Marta Formation, belongs to the giant sauropod group Titanosauria, which were among the largest land animals. Historically, Antarctica has yielded very few dinosaur fossils, with only about six taxa described, making this discovery a vital addition to our understanding of ancient Gondwana. The identification of this vertebra not only fills a major gap in the continent's fossil record but also highlights the global connections of dinosaur evolution.
