11-year-old Ruby Reynolds and her father found a potential largest marine reptile fossil, an ichthyosaur jawbone, in Somerset, UK.

11-year-old Ruby Reynolds and her father discovered fossilized remains of a jawbone from what may be the largest marine reptile ever known, an ichthyosaur, on a beach in Somerset, UK. The remains are estimated to belong to a creature that could reach lengths of 25 meters (82 feet), similar to a blue whale. Researchers believe the specimen could represent the largest marine reptile ever recorded, and further evidence is required to conclusively determine its size.
