Fossilized pellets reveal giant penguins' coastal feeding habits

Paleontologist Dirk Knaust analyzed drill cores from Norwegian oil drilling and found fossilized pellets that indicate giant penguins regurgitated shells and debris on land. This provides new evidence about their behavior, suggesting they lived at sea but came ashore to spit up indigestible material. The finding is based on a single study and may be limited by the sample size.
