Finally a good news!
According to the current knowledge of Earth's paleontologists, the andrewsarchus was the largest carnivorous mammal ever lived on the planet. Although most modern reconstructions saw it as an animal more similar to a warthog than to a wolf or in any case an active predator, it was still very large by the standards of a mammal. It reached the impressive length of more than five meters and a height at the withers of almost two meters.
By comparison the Bengal tiger was just a adorable kitten, and even the massive polar bears were smaller than it.
