Frontier · Unverified Leads

Leads — likely shark tooth ground, scored by evidence.

These are unverified prospects, not curated locations. They're ranked from explicit evidence only: fossil-bearing formations, marine depositional fit, exposure mechanics, concentration potential, access clarity, and confidence. Restricted sites are shown only as contact-first targets — never as implied open access.

Rank for
Method: scores are deterministic. No LLM freeform prospect picking, no invented geology, and no implied permission. If evidence or access is weak, the score drops.

Aurora Mine Access Days

Restricted mine-adjacent access with some of the strongest public evidence anywhere in North America for giant Miocene teeth and exceptionally preserved material.

Why the logic likes it
  • Pungo River Formation is one of the richest Miocene marine vertebrate units in the country
  • Active phosphate extraction continuously exposes fresh fossil-bearing sediment
  • Documented museum collections and public finds strongly support both trophy and diversity potential

Access and next step

Best route is through Aurora Fossil Museum event access and official mine-day channels.

Do not attempt access outside official events or operator-managed permissions. This is not open casual collecting.

North Sulphur Reset Bars

Access and next step

Use public crossings and permissioned land only. This is public in slices, not everywhere.

Do not extrapolate from a bridge crossing to the whole corridor. Private land and dangerous mud are real constraints.

Ernst Quarries / Sharktooth Hill Dig Access

Round Mountain Silt access remains one of the best logic-backed California targets when you can get onto operator-managed spoil or quarry ground.

Why the logic likes it
  • The Round Mountain Silt is a proven Miocene marine fossil unit
  • Operator-managed spoil provides concentrated search material rather than dispersed beach lag
  • California preservation quality is often excellent in matrix-rich spoil contexts

Access and next step

Only pursue operator-managed access or established dig-day arrangements. Verify the operator directly before travel.

Treat as guided or operator-controlled only. Do not assume open public entry just because a dig day is advertised somewhere online.

Surfside Shell Ridges and Front Cuts

A strong public Gulf prospect because the geology is proven and the reset mechanism is easy to describe: fronts strip, shell ridges concentrate, lag becomes huntable.

Public beach prospect. Best used with the live condition layers already in Toothhound.

A calm week can bury the whole setup. This is a condition-sensitive prospect, not a constant producer.

Why the logic likes it
  • Remote beach means less pressure than town-access beaches

  • The site is already known for broad beachcombing diversity, which usually tracks with strong concentration behavior

Public, but functionally remote. Treat logistics and weather as part of the access question.

Travel only after checking conditions and access. This is not a casual go-anytime recommendation.
