Reply to comment by bigwavedave000 in New species identified, from 3D models of prehistoric penguins’ humongous humerus, may be the largest penguin ever to have lived. ~350-pound ‘Kumimanu fordycei’ weighed as much as an adult gorilla; waded the waters off New Zealand about 60 million years ago by marketrent
