These now-extinct cephalods were the predecessors of modern-day squid, octopus, and nautilus and survived for nearly 335 million years! Young readers will discover how these shelled creatures came in myriad shapes, sizes, and designs, and how they managed to outlast several mass extinctions until about 65 million years ago.
