When some curious summer campers at the Hamilton Junior Naturalist Club (Junats) set out on an expedition to Kawhia Harbour on New Zealand's North Island, they were just hoping to find some small crustacean fossils. Instead, they discovered a well-preserved skeleton of a new species of a giant penguin that inhabited the area between 27 to 30 million years ago.
