Whether you’re a seasoned collector or someone looking to start your fossil journey, our collection showcases incredible examples of fossilized fish that have been immaculately preserved for millions of years. Let’s explore what makes these fossils unique and why so many collectors turn to us for authentic, top-quality pieces.
Consider these key aspects when exploring our collection of fish fossils on sale:
A Glimpse into Prehistoric Waters: The Green River Formation
The Green River Formation, located in the western United States, is a treasure trove of prehistoric aquatic life. This Eocene-aged deposit—formed around 50 million years ago—was once home to vast lakes filled with fish and other fauna. Over time, these organisms became buried in fine sediment that allowed for extraordinary fossil preservation.
We proudly feature green river fish fossils from this world-renowned site, including well-known genera like:
● Diplomystus – Recognizable by their upturned mouths and elongated bodies.
● Knightia – Often found in groups, these small fish are among the most frequently discovered.
● Mioplosus – A predatory species showcasing impressive jaw detail.
● Phareodus – Known for their deep bodies and detailed fin structures.
● Priscacara – With spiny fins and rounded shapes, these fish resemble modern sunfish.
These fossil specimens are preserved so clearly that their bones, scales, and even skin impressions are visible to the naked eye—offering a rare window into ancient lake ecosystems.
Split Fish Layer vs. 18-Inch Layer: Two Exceptional Fossil Sources
At Buried Treasure Fossils, we understand the value that provenance and layer context bring to a fossil. That’s why we offer fossil fish from two distinct layers of the Green River Formation: the split fish layer and the 18-inch layer.
● Split Fish Layer: This layer is known for delivering detailed and delicate specimens. When split apart, the thin limestone reveals stunning impressions of fish in natural repose.
● 18-Inch Layer: Fossils from this layer are typically extracted using careful excavation, resulting in slabs with deep contrast and museum-quality presentation. These specimens are perfect for display purposes and highly sought after by collectors.
Both layers offer unique advantages, and we ensure that each piece from either layer maintains the highest standards of authenticity and visual impact.
Beyond the Green River: Fossil Fish from Italy and Morocco
While the Green River Formation remains a crown jewel in the fossil world, we also bring you fascinating fish fossils from other historic locations like Italy and Morocco. These international finds broaden the scope of our collection and allow you to explore the ancient aquatic biodiversity of different prehistoric environments.
● Italian Fossil Fish: These pieces often come from formations renowned for their detail and preservation quality.
● Moroccan Fossil Fish: Known for their rich coloration and dramatic appearance, Moroccan specimens add variety and charm to any collection.
Each fossil is hand-selected by our team to meet our strict quality standards, ensuring that what you receive is not only authentic but also visually compelling.
