Somerset Shores Yield Historic Discovery: 11-Year-Old Unearths Possible Largest Marine Reptile Fossil

In a remarkable discovery along the coast of Somerset, an 11-year-old girl has stumbled upon fossils that could belong to the largest marine reptile ever identified, according to paleontology experts. This groundbreaking find may shed new light on creatures that roamed the seas approximately 202 million years ago.

A team of paleontologists suggests these ancient remains unearthed by a young beachcomber could be from a gigantic ichthyosaur, a formidable marine predator from the dinosaur era. This newly identified species, named Ichthyotitan severnensis or “giant fish lizard of the Severn,” is thought to have navigated the world’s oceans at the tail end of the Triassic period.

Dr. Dean Lomax, a University of Bristol paleontologist and research co-author, expressed excitement over the scale of the discovery. “This leviathan likely represents the largest marine reptile formally recognized,” he noted, comparing the creature’s estimated size—about 25 meters long, akin to a blue whale—to known ichthyosaur fossils.

Despite relying on partial bone fragments, which requires cautious size estimation, Dr. Lomax emphasized the significance of the find. “Simple scaling from these pieces is commonly used to deduce the full size of such massive animals, particularly when few comparative samples exist,” he explained.

The discovery journey began when Justin Reynolds and his daughter Ruby, now credited as co-authors, found the initial pieces of a jawbone on Blue Anchor Beach in May 2020. They quickly involved Dr. Lomax, who expanded the search, leading to a collaboration with other fossil enthusiasts, including Paul de la Salle, a recognized figure in marine paleontology.

This isn’t the first time Somerset’s shores have revealed such treasures. De la Salle had previously uncovered a jawbone from a potential new ichthyosaur species in 2016, sparking further research by Lomax and his colleagues. Fitting the newly found fragments together, the team confirmed they belonged to the same species as De la Salle’s find, solidifying the significance of their discovery.

These findings not only hint at a previously unknown gigantic creature but also suggest these ichthyosaurs were among the last survivors of their lineage before the mass extinction at the Triassic’s close.

Adding an expert perspective, Dr. Nick Fraser from the National Museums Scotland, who reviewed the findings, found the identification of the fossil as part of an ichthyosaur’s lower jaw compelling. “The sheer size of the fossil suggests its owner was an extraordinarily large beast, potentially one of the greatest marine reptiles to have ever existed,” he stated, although he expressed reservations about officially classifying it as a new species due to the incomplete nature of the fossils.

This discovery highlights not only the rich prehistoric life of Earth’s ancient oceans but also the ongoing contributions of amateur fossil hunters in uncovering our planet’s deep history.
