Argentine scientists have discovered fossils of a two-metre tall penguin that lived in Antarctica 34 million years ago.
Paleontologists with the Natural Sciences Museum of La Plata province said on Tuesday the remains were found on the continent.
"This is the largest penguin known to date in terms of height and body mass," said Carolina Acosta, who noted that the record had been held by emperor penguins, which reach heights of 1.2 metres tall.
Next summer, the team will seek additional fossils of the newly discovered species, as well as information about its anatomy and how the giant penguin might have moved.
Previous finds from prehistoric penguins indicated they did not sport the black and white feathers the birds are known for today, but had reddish-brown and grey plumage.
