While wading on the beach, a 9-year-old unearths a strange object.

Beachcombers’ treasures are usually limited to fairly common seashells, sea glass, driftwood, and, now and then, a message in a bottle. Nonetheless, rummaging through the surf for something more interesting than an old candy wrapper can be entertaining.

Occasionally, fossils wash up on the beach, delighting beachgoers sifting through the sand for more minor finds. Fossil collecting is a unique hobby that combines time spent outside with ancient history.
