Fossil Hunting in South Carolina

intermediate friendly Shark teeth (including megalodon)Whale bone fragmentsFossil shellsRay dental plates

South Carolina is a bucket-list destination for shark tooth hunters. The Cooper River near Charleston has produced some of the largest and best-preserved megalodon teeth ever found, and the state’s beaches are consistent producers of Cenozoic marine fossils.

Why South Carolina?

The South Carolina Coastal Plain sits atop thick layers of marine sediment deposited when the Atlantic Ocean covered the region during the Eocene and Oligocene epochs. The Cooper River and its tributaries cut through these fossil-rich formations, constantly eroding teeth, bones, and shells into the riverbed. The combination of abundant source material and active erosion makes this one of the most productive shark tooth collecting areas in the world.

What You’ll Find

Shark teeth (Eocene through Pliocene, ~5-40 million years old):

  • Megalodon teeth — the crown jewel, ranging from fragments to palm-sized specimens over 5 inches
  • Great white, mako, sand tiger, and bull shark teeth — common in river and beach deposits
  • Ray dental plates — flat, pavement-like crushing teeth

Marine mammals and reptiles:

  • Whale bone fragments, occasionally with preserved surface texture
  • Dolphin and sea turtle remains (less common)

Invertebrates:

  • Fossil oysters, scallops, and gastropods from the Ashley and Chandler Bridge Formations

Best Time to Visit

  • Fall through spring: Most comfortable weather and clearest water conditions for diving
  • After storms: Beach collecting improves dramatically as wave action turns over sediment
  • Low tide: Essential for beach collecting at Edisto and Folly Beach

Tips for South Carolina Collecting

  1. Get your hobby dive license before visiting the Cooper River — it is required and enforced
  2. Hire a local guide for your first Cooper River dive — conditions are challenging with zero visibility
  3. Walk the wrack line on beaches — teeth often concentrate among shell hash at the high-tide mark
  4. Bring a mesh sifting screen — sifting gravel on beaches dramatically increases your find rate
  5. Start at Edisto Beach if you are a beginner — no diving required and teeth are found regularly

Collecting Sites

Cooper River (Diving)

Free Public Access

Berkeley and Dorchester Counties

The blackwater Cooper River is world-famous for megalodon teeth. Divers feel along the dark river bottom for fossils eroded from Oligocene and Eocene formations. This is a dive-only site — visibility is near zero, so collectors work by touch. A South Carolina hobby dive license is required.

Edisto Beach

Free Public Access

Edisto Island, Colleton County

The beach at Edisto Island regularly produces shark teeth and fossil bone fragments washed from offshore deposits. Walk the tide line after storms for the best results. No diving required — this is a surface collecting site.

Summerville Area Ditches and Creeks

Private (Permission Needed)

Summerville, Dorchester County

Construction sites, drainage ditches, and creek beds around Summerville cut through the Ashley and Chandler Bridge Formations. Permission from landowners or construction companies is needed but can yield excellent specimens.

Folly Beach

Free Public Access

Folly Beach, Charleston County

Similar to Edisto, Folly Beach produces shark teeth and other marine fossils along the tide line, especially after storms and renourishment projects that bring up offshore sediment.

Legal Rules for South Carolina

Fossil collecting on South Carolina beaches is legal. Diving in the Cooper River requires a South Carolina hobby dive license (available online through SCDNR). Collecting from construction sites and private land requires permission. Vertebrate fossils found on state or federal land may be subject to restrictions. The Cooper River is tidal — divers must be experienced with current and low-visibility conditions.
