AI Summary

An international team of paleontologists, including researchers from McGill University, uncovered remarkably large rodent fossils in the Bang Mark Pit of the Krabi lignite mine in Krabi Province, southern Thailand. The fossils consist of a lower second molar and a lower incisor belonging to a new species named Yakamys sirindhornae. Radiometric dating places the specimens at about 34 million years old, in the mid‑Paleogene period. Published in Scientific Reports, the discovery expands the known timeline and geographic range of rodent gigantism, showing that large‑bodied rodents existed much earlier than previously thought.
