Researchers discovered the first mammal footprint in Antarctica, approximately 55 million years old. The study was published last month in the journal Polar Biology.
The specimen, identified as T-373, consists of a set of fossil impressions found at the Fossil Hill Formation, on King George Island, in Antarctica.
The fossil record of Antarctica continues to be quite scarce, especially regarding terrestrial mammals that inhabited the continent in the past. Fossils, footprints and other traces can offer important information about the environments that ancient animals frequented, as well as their distribution and movement.
Information about the exact identification of the animal that left the footprint is not available in the article.
