Girl on a UK beach uncovers jaw of giant Triassic ichthyosaur
On a Somerset beach, 11-year-old Ruby Reynolds and her father found jaw fragments dating to about 202 million years ago, leading scientists to name Ichthyotitan severnensis, a colossal ichthyosaur potentially around 82 feet long—the largest marine reptile known—based on skeletal jaw evidence; the discovery, described in PLOS ONE, highlights how citizen science and coastal erosion can rewrite natural history.
