Which Prehistoric Predators Could Take Down A Blue Whale?

The blue whale is the most massive animal alive today, famous across the world for its grace, power, and immense form. They’re filter feeders, swallowing thousands of gallons of krill at a time to sustain their titanic bodies, and adults range from well over a hundred to possibly over two hundred tonnes at maximum size. No aquatic predator exists in the modern day that hunts fully-grown blue whales in a one on one encounter, but what about the ancient past? What prehistoric carnivorous giants could stand a chance against the biggest animal on the planet?
