When it comes to collecting marine fossils, few specimens captivate collectors like the ancient shark teeth from the phosphate-rich Caldera region of the Atacama Desert in northern Chile. At Buried Treasure Fossils, we are proud to offer an exceptional collection of fossil shark teeth from this world-renowned site, including the highly sought-after Chile Megalodon tooth. These remarkable fossils date back to the late Miocene to lower Pliocene (approximately 4 to 6 million years ago), specifically from the Bahia Inglesa Formation. The combination of superb preservation, vivid coloration, and species diversity makes these teeth among the finest marine fossils known to collectors.
A World-Class Fossil Locality in Northern Chile
The Caldera phosphate mining area, near Copiapo in north-central Chile, has long been recognized for its geological richness. This land-based site, now a protected natural preserve, once yielded one of the most diverse and well-preserved marine fossil assemblages on the planet. The fossils recovered from this area—especially the shark teeth—are renowned for their near-perfect condition and extraordinary preservation.
Unlike many marine fossils found in river or ocean deposits, these Chilean shark teeth were buried in sedimentary rock layers far from today's shorelines. This unique preservation environment resulted in fossils that retain incredible detail, pristine edges, and vibrant colors, all hallmarks of authentic specimens from this historic site.
Museum-Quality Fossils: “The Best of Chile”
At Buried Treasure Fossils, we bring you what we proudly call “The Best of Chile.” Our hand-selected offerings feature museum-quality shark teeth from a broad range of species. Whether you're looking for a Chile Megalodon tooth, a record-breaking Great White tooth, or beautifully preserved examples of extinct species like Mako, Hexanchus, and Megachasma, you’ll find only the finest specimens in our collection.
What truly sets these fossils apart is their unmatched condition. With intact root structures, sharp serrations, and minimal wear, these shark teeth provide a rare glimpse into prehistoric marine life. Even collectors who have seen thousands of specimens are often stunned by the pristine condition of these Chilean fossils.
From the Ocean Floor to the Desert Sands
The fossils of the Caldera region tell a fascinating story of transformation. Once submerged beneath ancient seas teeming with massive predators, this area is now one of the driest deserts on Earth. Over millions of years, tectonic uplift and environmental shifts exposed these marine layers, preserving the fossils in land-based formations that allowed for careful collection.
This unique geologic history means that Chilean shark teeth are not only beautiful but scientifically significant. Their condition, diversity, and abundance have made the Bahia Inglesa Formation one of the most important sources of late Miocene-Pliocene marine fossils known to collectors around the world.
A Protected Site – Why Chilean Fossils Are Rare Today
Unfortunately, as of 2006, the Caldera phosphate mining operation was shut down, and the entire fossil area was designated a protected natural preserve. This decision—while important for conservation—has significantly limited the availability of new fossils from the site. All Chilean shark teeth available today must come from older, pre-2006 collections, making these fossils increasingly rare.
At Buried Treasure Fossils, we are committed to offering only legally and ethically sourced specimens. The fossils in our Chilean collection are guaranteed to be authentic and sourced from historical collections accumulated before the site’s closure. This means that every piece you see on our site is a piece of history—one that is no longer collectible from its source and available only in limited supply.
Highlights from Our Chilean Collection
Our Chilean fossil selection features a range of iconic shark species that once roamed ancient oceans:
● Megalodon – The apex predator of its time, with teeth that can exceed six inches in length. A Chile Megalodon tooth is one of the most prized additions to any fossil collection.
● Great White Shark (Carcharodon carcharias) – Including record-size teeth and transitional forms that represent the evolutionary bridge from earlier species.
● Mako Shark (Isurus planus and Isurus hastalis) – Known for their sleek, blade-like teeth.
● Sixgill Shark (Hexanchus sp.) – Representing one of the oldest shark lineages, still surviving in today’s oceans.
● Megamouth Shark (Megachasma sp.) – Rare and intriguing, these teeth are from a deep-sea species with few modern sightings.
Each tooth is a window into a different chapter of prehistoric marine history—one that we are proud to help you explore and preserve.
