Scientists have announced the discovery of the oldest-known fossil of a giant tadpole, which dates back approximately 161 million years. This remarkable find not only surpasses the previous record-holder by about 20 million years but also offers insights into ancient amphibian behavior and ecology. The tadpole fossil measures 6.3 inches long and is noted for its exceptional preservation, including some soft tissues still intact. Researchers believe this specimen could reshape understanding of the lineage of stem tetrapods, as it comes from a lineage thought to have been extinct for 40 million years prior to its existence. This discovery adds to the growing body of paleontological findings, including other significant fossils from ancient mammals and dinosaurs in various locations, including Colorado and Mongolia's Gobi Desert.
