Summary

An ancient rodent of extraordinary size has been identified from fossils uncovered in a mine in southern Thailand. The discovery, made by an international team of paleontologists that includes scientists from McGill University, provides new evidence that giant rodents appeared much earlier and in more parts of the world than previously believed. The researchers found "remarkably large" fossilized teeth belonging to a previously unknown species called Yakamys sirindhornae . This prehistoric rodent lived approximately 34 million years ago, during the middle of the Paleogene period.
