This new jawbone changes our picture of ichthyosaurs dramatically — not only does it beat out the largest - known shastasaurid, the 69 - foot Shonisaurus sikanniensis, it may reveal that mysterious bones discovered in other parts of the UK are also from
giant ichthyosaurs:
We argue here that the Aust bones, previously identified as those of dinosaurs or large terrestrial archosaurs, are jaw fragments from
giant ichthyosaurs.»

giant dolphins.
