Diver Finds 4-Foot Mastodon Tusk Off Florida Coast

Alex Lundberg was exploring the seabed 25 feet below Florida's Gulf Coast when something caught his eye in April 2024. What started as a routine fossil hunt turned into the discovery of a lifetime.

The marine biology graduate initially mistook the object for driftwood. But as he cleared away the sand, the piece kept expanding beyond anything he'd seen before.

"It just keeps getting bigger and bigger," Lundberg said. "I'm like, this is a big tusk."

The fossil measured 4 feet long and weighed 70 pounds, making it the largest intact mastodon tusk section ever recovered from the waters near Venice, Florida. While complete tusks could reach nearly 16 feet, finding any preserved section this size is remarkable.

Lundberg wasn't new to underwater fossil hunting. He'd held an official collecting permit since 2019 and had previously found mammoth teeth, ancient jaguar bones, dire wolf parts, and smaller tusk fragments in the same location.

But this discovery stood apart from all the rest. The tusk now sits in a glass case in his living room, a window into an Ice Age world that vanished thousands of years ago.

Why This Inspires

Lundberg's find reminds us that prehistoric wonders still hide beneath our feet and waves. Mastodons roamed North America for millions of years before going extinct, and their fossils help scientists understand how these elephant relatives lived and what their world looked like.

These ancient creatures had straighter tusks than their mammoth cousins and cone-shaped tooth cusps perfect for crushing twigs and vegetation. They split from the elephant family tree about 25 million years ago, creating their own unique branch of prehistoric life.

The discovery also highlights how citizen scientists contribute to our understanding of natural history. Lundberg's years of patient searching and proper documentation help researchers piece together Florida's prehistoric past.

Under Florida law, vertebrate fossils found in state waters belong to the Florida Museum of Natural History. Lundberg was required to report the find when renewing his permit in December 2024, ensuring the discovery could be studied and shared with future generations.

Every fossil tells a story about life on Earth before humans walked the planet, and this massive tusk is no exception.
