Penguin poop gives Antarctic cloud formation a boost
Penguin poop provides ammonia for cloud formation in coastal Antarctica, potentially helping to mitigate the impacts of climate change in the region.
- Paleontology
Earth’s first waterfowl may have lived in Antarctica 69 million years ago
A few fossilized body parts hinted at an enigmatic bird's close ties to waterfowl like ducks and geese. A newfound skull may bolster that idea.
