 Palaeeudyptes klekowskii

Palaeeudyptes klekowskii, also known as the colossus penguin, was a species of the extinct penguin genus "Palaeeudyptes".It was until recently thought to have been approximately the size of its congener "Palaeeudyptes antarcticus", which would mean it was somewhat larger than the modern emperor penguin, but a new study shows it was in fact almost twice as tall.
