    Study Notes

    Ichthyosaur Discovery

    • A new, massive ichthyosaur species, Ichthyotitan severnensis, was discovered by amateur paleontologists Justin Reynolds and his daughter Ruby.
    • The fossils were found on Blue Anchor Beach in Somerset, England.
    • The area is known for its rich Triassic-era fossil deposits.
    • The discovery began in spring 2020 with the finding of a small, oval fossil.
    • Additional, larger fossilized bone fragments were found by Ruby.
    • Experts confirmed the fossils were from an ichthyosaur.
    • The team, led by Dr. Dean Lomax, worked to recover more fossils, culminating in the reconstruction of a section of the lower jaw in October 2022.
    • Estimated length of the complete lower jaw: over 6 feet (1.8 m).
    • Estimated total length of the ichthyosaur: a staggering 80 feet (24 m).
    • The new species was classified based on bone fragments, along with a similar ichthyosaur found in 2016.
    • The name Ichthyotitan severnensis translates to "giant fish lizard of the Severn."
    • Justin and Ruby were co-authors of the study published in PLOS One in April 2024.
    • Ichthyosaurs dominated seas during the Triassic and Jurassic periods (251-145 million years ago).
    • They were marine reptiles, similar in appearance to dolphins and whales.

    Ichthyosaur Attributes and Discovery Context

    • Ichthyosaurs were members of the reptile family.
    • The discovery highlights the value of amateur paleontologists in contributing to scientific research.
    • The discovery process demonstrates the importance of persistence and collaboration.
    • Finding a fossil is often a rare occurrence. (95% of finds are discarded as ordinary rocks)
