Phorusrhacos stood around 2.5 meters tall and weighed approximately 130 kilograms (Alvarenga & Höfling, 2003). It was nicknamed the "Terror Bird" for obvious reasons: it was one of the largest carnivorous birds to have ever existed, and the former wings formed arm-like structures with claws shaped like a meathook for tackling prey, which was then killed with the massive beak. The lion is a well-known, truly carnivorous member of the order Carnivora. ...
