Scientists have shown that ammonites -- an extinct type of shelled mollusk that's closely related to modern-day nautiluses and squids -- made homes in the unique environments surrounding methane seeps in the seaway that once covered America's Great Plains. The findings provide new insights into the mode of life and habitat of these ancient animals.
