Summary
British paleontologists found the remains of an ichthyosaur, a marine reptile that could give the whales some competition. The bone measured 2.3 meters—compared to the surangular found in the Shonisaurus sikanniensiensiensis skeleton, it was 25 percent larger. In 1846, five large bones were found at the Aust Cliff near Bristol in England. They were dubbed “dinosaurian limb bone shafts’s” and exhibited in the Bristol Museum. In 2005, a British paleontologist then working at the University of Bridgeport, noticed something strange in one of The last known ichthyosaurs went extinct 90 million years ago. They survived but never reached similar sizes again. They faced competition from plesiosaurs and sharks that were more agile and swam much faster.
