Paleontologists have discovered fossil remains belonging to an enormous 'toothed' bird that lived for a period of about 60 million years after dinosaurs.
Scientists were struggling to keep track of illegal fishing in international waters and the seabirds it threatened. Then they had an idea.
New Zealand is home to more seabirds than any other country, and many species are already under pressure from climate change and over-fishing. Plastic pollution could push some closer to the brink.
