The great auk (Pinguinus impennis), also known as the penguin or garefowl, is an extinct species of flightless alcid that first appeared around 400,000 years ago and became extinct in the mid-19th century. It was the only modern species in the genus Pinguinus.
Palaeeudyptes klekowskii is an extinct species of the penguin genus Palaeeudyptes.It was previously thought to have been approximately the size of its congener Palaeeudyptes antarcticus, somewhat larger than the modern emperor penguin, but a 2014 study showed it was in fact almost twice as tall, earning it the nickname “Mega Penguin”.
Palaeeudyptes is an extinct genus of large penguins, currently containing four accepted species.They were probably larger than almost all living penguins, with the smaller species being about the size of an emperor penguin, and the largest species, Palaeeudyptes klekowskii, estimated to reach 2 meters (6.6 ft) long (measuring tip of beak to tail) and weighed up to 116 kg (256 lb).

Traditionally, most extinct species of penguins, giant or small, had been placed in the paraphyletic subfamily called Palaeeudyptinae. More recently, with new taxa being discovered and placed in the phylogeny if possible, it is becoming accepted that there were at least two major extinct lineages.
Inkayacu, along with other extinct penguins from Peru, are often referred to as giant penguins because of their large size.
