       Sometimes confused with the similarly named ichthyosaur Eurhinosaurus,‭ ‬Eurhinodelphis was a Miocene era cetacean that resembled a long snouted dolphin.‭ ‬Another similarity to dolphins is the asymmetrical brain which means one side was different than the other.‭ ‬Additionally Eurhinodelphis had extremely well developed hearing and is considered to have possibly hunted by echolocation.‭
       The long jaws,‭ ‬particularly the upper which extends beyond the lower has been interpreted as being the main prey killing adaptation.‭ ‬Like with sword fish,‭ ‬palaeontologists think that Eurhinodelphis would have swum into a shoal of fish and thrashed its long snout about to inflict injuries upon the fish.‭ ‬Once injured the fish could not swim and move with the rest of the shoal and became easy prey.
