Just heard a new species of Ichthyosaur has been discovered in England. It's been named Ichthyotitan and is estimated to have measured a whopping 25 metres long. Currently, Shastasaurus, at an estimated length of 21 metres, is the largest known Ichthyosaur, but it seems Ichthyotitan may have been a good three to four metres longer.
