Biggest Reptile Fossil Ever Found Discovered by an 11-Year-Old in UK

In 2020, Ruby Reynolds and her father, Justin, unearthed a remarkable discovery during fossil exploration on Blue Anchor Beach in Somerset. The fossilized jawbone segment they excavated was attributed to an immense ichthyosaur, a prehistoric marine reptile inhabiting the waters around 202 million years ago, during the Triassic epoch. This find illuminates the breadth and complexity of ancient marine ecosystems, highlighting the important role amateur fossil hunters may play in scientific discovery.


Dr. Dean Lomax, a paleontologist at the University of Manchester, identified the jawbone, estimated to surpass two meters in length. Recognizing its significance, Dr. Lomax and his research team orchestrated further excavations, yielding additional fossil fragments, including the distinctive surangular bone situated posteriorly on the jaw. These findings unveiled a novel species of ichthyosaur, designated Ichthyotitan severnensis. Reaching lengths of up to 25 meters, comparable to contemporary blue whales, Ichthyotitan severnensis represents the largest formally documented marine reptile to date, surpassing even the most sizable known specimens of other ichthyosaurs.


The new species, Ichthyotitan severnensis, was reported in detailed research published in the journal PLOS One. Interestingly, Justin, Ruby, and Paul de la Salle, another fossil collector engaged in the finding, were designated co-authors of the article, emphasizing amateur fossil hunters' essential contribution to scholarly research.


The fossils, comprising the jawbone and assorted bone fragments, are slated for public display at the Bristol Museum and Art Gallery, offering an opportunity for visitors to marvel at these ancient sea creatures and delve deeper into their captivating narrative. The revelation of Ichthyotitan severnensis has sparked renewed interest among scientists and scholars, passionate about the ancient marine reptiles that once inhabited the waters. It has also prompted concerns about the evolutionary history and ecological significance of these gigantic organisms, opening up new areas for future investigation.


Dr. Lomax applauded Ruby's contribution to the study, stating that she is now a published scientist and comparing her to Mary Anning, a well-known 19th-century fossil collector. Ruby emphasized her delight at being a part of such a momentous scientific find, underscoring the role of amateur fossil hunters in unraveling the secrets of the past.


Marcello Perillo, a master's student at the University of Bonn in Germany, conducted in-depth analyses of the fossils' internal structures. His research corroborated the ichthyosaur origin of the bones and revealed that the specimen was in a stage of active growth at the time of its demise. This suggests that Ichthyotitan severnensis had the potential to attain even larger dimensions, further enhancing the intrigue surrounding this remarkable find.


The discovery of Ichthyotitan severnensis demonstrates the power of curiosity and the value of citizen research. It serves as a reminder that revolutionary discoveries may emerge from unexpected places and that everyone, regardless of age or experience, can help us comprehend the natural world.


As scientists continue to research the fossils and uncover the secrets of Ichthyotitan severnensis, it is anticipated that future excavations will reveal more about these ancient sea giants and their role in the evolution of life on Earth. Every new discovery propels us nearer to grasping the intricate and diverse mosaic of life that has evolved on our planet over millions of years.
