new discovery about ancient marine predator

World's oldest sonar system unearthed: Whale fossils reveal marine mammals using 'sound to see' 32 MILLION years ago
    28 million-year-old fossil was of a species of whale called Cotylocara macei
    Skull had air pockets similar to that used by dolphins to send sound beams
    Find places origin of technique, called echolocation, to 32m years ago
    This was relatively soon after whales, around 35 million years ago, split into two groups: active hunters and a toothless baleen species

Could this explain how lake cryptids hunt prey and therefore don’t surface very often? Just a thought for the weekend.
