Arthur’s Field Diary: The Shark’s Tooth Lagoon

Arthur’s Field Diary: The Shark’s Tooth Lagoon

Somewhere between the Miocene and my monocle’s polish.

Illustrated map of prehistoric Florida—shallow seas and island chains along the ancient coast.

Ahoy, dear reader! Permit me—Arthur, your dapper guide—to recount a tale from the deep past, when Florida was not a sunlit peninsula but a necklace of islands strung across a warm, shallow sea.

“We shed thousands of teeth in a lifetime— the seabed becomes an accidental archive of enamel.”

In that lagoon, storms shifted sands and rivers poured silt into the shallows. Each flood tucked teeth deeper, layering them with shells, coral, and bones. Thus were born the Myakka fossil beds—a pantry of prehistory beneath today’s riverbanks.

He scoops gravel from the river and—lo!—a tooth emerges, blackened by time yet wickedly sharp. One fossil, two oceans: the ancient lagoon of my kin and the winding Myakka of today.

Next time you hold one of these glossy relics, tip your hat—or monocle—to the sharks who left a treasure map in enamel. Fossils are time’s calling cards, reminding us the world beneath our feet once moved to different tides.
