    Study Notes

    Ichthyotitan Severensis Discovery

    • The discovery of a second jaw piece confirms that the giant bones belong to the same enormous species, Ichthyotitan severensis.
    • The creature's name refers to its apparent size and the River Severn Estuary, where the second jaw fragment was discovered.

    Fossil Significance

    • Ichthyotitan severensis is the first giant ichthyosaur discovered in the latest part of the Triassic Period.
    • Prior to this discovery, giant ichthyosaurs were only found in older rocks in North America and Asia.
    • The discovery of Ichthyotitan severensis provides a new picture of life during a time and in a part of the world where such giants haven't been found before.

    Fossil Characteristics

    • The jaw bones are six-foot-long, indicating the animal's enormous size.
    • The reptile is only known from two bones that made up part of the lower jaw, called the surangular.
    • More fossils are needed to determine exactly how Ichthyotitan differed from other ichthyosaurs.

    Research and Publication

    • The discovery is described in a new paper published in the journal PLOS ONE.
    • Paleontologists sound a note of caution on the exact dimensions of Ichthyotitan due to the limited fossil evidence.
