How to Identify a Real Megalodon Tooth

A genuine Otodus megalodon tooth is a fossil between roughly 3.6 and 23 million years old: stone-heavy, finely serrated on both edges, with a dark chevron-shaped bourrelet and a porous, bilobed root. A resin cast can be poured by the dozen. This guide covers the anatomy of a real tooth, the marks of authenticity, the red flags of a fake, the honest difference between a fake and a restored tooth, safe at-home checks, and why provenance and a COA matter.

South Carolina Fossil Hunting: Laws, Licenses & Where to Look

South Carolina is one of the best fossil states, and one of the most specific about the rules. This guide explains how the law changes by where you stand: the SCIAA hobby license for the rivers (with SCDNR on the water), what you can collect on the beach without one, private-land permission, and the federal PRPA. General information, not legal advice.

How to Grade and Value Fossil Shark Teeth

A fossil shark tooth's value rarely comes down to size alone. This curator's guide covers the factors that actually drive grade and value: slant height measured correctly, completeness, enamel quality and color, serrations, tip and root condition, percent restoration, pathology, and locality. It explains a practical gift / collector / investment framing, why bigger isn't automatically better, why a disclosed repair is fine but a hidden one isn't, and how to read a listing and a COA.

River vs Beach Fossil Finds in the Lowcountry

A field guide to telling river fossil shark teeth from beach fossil shark teeth in the SC Lowcountry. Learn how fossils erode from submerged Oligocene and Miocene formations into blackwater rivers like the Cooper and Edisto, giving them deep color, smooth patina, and fine preservation, versus how surf and beach renourishment deliver smaller, more worn teeth to Folly and Edisto Beach. Includes a comparison table, the realities of collecting each, and what origin means when you buy.

South Carolina Fossil Formations Explained

A plain-English guide to the South Carolina coastal-plain geologic column and the fossils each layer yields — the Oligocene Cooper Group (the Ashley and Chandler Bridge Formations, with early whales, dolphins, and Otodus angustidens shark teeth), the Miocene Hawthorn Group phosphates, and the Pliocene-to-Pleistocene Ice Age deposits that produced the Columbian mammoth. With verified, well-hedged ages and why the correct formation matters for dating and valuing a specimen.

How to Clean and Display Fossils the Right Way

A fossil shark tooth survives millions of years underground, then takes most of its damage on your shelf. This guide covers how to clean and display fossil shark teeth the right way: the gentle cleaning that helps, the acids and shortcuts that destroy value, the real enemies in a display case (UV, humidity swings, handling oils), how to stabilize flaky matrix, and how to label a specimen so its species, locality, and provenance endure.

The Otodus Shark Lineage: Megalodon and Its Ancestors

A curator-led guide to the megatooth (Otodus) shark lineage and how to tell the species apart by their teeth. Walk the sequence from Otodus obliquus through auriculatus, angustidens, and chubutensis to megalodon as the lateral cusplets shrink and vanish, the serrations refine, and the crown broadens into a cutting blade. Includes the honest Carcharocles-vs-Otodus naming history, why megalodon was not the great white's ancestor, and South Carolina's role as Oligocene angustidens country.

The Columbian Mammoth: South Carolina's State Fossil

The Columbian mammoth is South Carolina's official state fossil, designated in 2014 after an eight-year-old's letter set off a memorable legislative saga. This guide covers the full story: the roughly 1725 Stono discovery often called one of North America's first correct fossil IDs, how it differed from the woolly mammoth, what teeth, ivory, and bone turn up here, and a careful, hedged look at the law on collecting and selling Ice Age fossils.
