Scientists have uncovered the twee remains of one of the smallest extinct penguin species ever found, which waddled around New Zealand around 3 million years ago.

Researchers unearthed two fossilized skulls belonging to the newly discovered species, named Wilson's little penguin (Eudyptula wilsonae), in the southern Taranaki region of the country's North Island. The shape of the skulls, which belonged to a fully grown adult and a juvenile, are remarkably similar in both size and shape to little penguins (Eudyptula minor), which still exist today and are the smallest living species of penguin.
