In Depth

       Saurodon is a genus of Carnivorous fish that swam in the world‭’‬s oceans during the Late Cretaceous.‭ ‬Saurodon had a long and slender body similar to the modern day barracuda.‭ ‬Also like a barracuda,‭ ‬the lower jaw of Saurodon projected in front of the upper,‭ ‬though in Saurodon this projection was far more extreme,‭ ‬and in some specimens this lower jaw is just beyond double the length of the upper jaw.‭ ‬This likely signifies a feeding specialisation that helped Saurodon to effectively hunt other fish,‭ ‬perhaps striking them from below and trying to swallow as much as they could to prevent their prey from escaping.
