Scientists have discovered that what is now New Zealand was once inhabited by a tall and elegant species of penguins 25 million years ago.
The bird measured over 4ft in height and exhibited a slimmer figure than contemporary penguins, characterized by its long beak and flippers.
The Maori name given to it was Kariuku, which translates loosely to ‘diver who returns with food’.
A reconstruction of the penguin was created using two distinct fossil skeletons.
According to lead scientist Dr. Dan Ksepka from North Carolina State University in the U.S., ‘Kairuku was, by penguin standards, an elegant bird, boasting a slender body and long flippers, complemented by short, thick legs and feet.’
Dr. Ksepka remarked, ‘The location offered an excellent environment for penguins, providing both abundant food and safety.’
‘At that time, most of New Zealand was submerged, leaving behind isolated, rocky land masses that shielded the penguins from potential predators while ensuring a bountiful food supply.’
Researchers are optimistic that the reconstruction of Kariuku will enhance understanding of the evolution of giant penguins.
Dr. Ksepka stated, ‘This species allows us to gain a more comprehensive insight into giant penguins as a whole and may help ascertain the extent of their range during the Oligocene period.’
