Let’s Collect Rocks and Shells

A tiny animal builds a sculpted house, then hides it in plain sight among rocks and seaweed. Can you spot the shell before its maker disappears?

In this late-20th-century field guide, Shell Union Oil Corporation turns beaches, tide pools, and other natural hiding places into a collector’s hunting ground. Young explorers meet the mollusks behind the shells, learn how bivalves and spiraling univalves are built, and discover names as fanciful as Lion’s Paw and Bleeding Tooth. The book also opens the door to collecting rocks, inviting readers to look closer at the natural treasures around them. But finding a specimen takes a sharp eye—and knowing where to search is only the beginning. What might be concealed in the next tide pool, or beneath your feet?
