New specimens have just arrived and will be available on our website very soon after a bit of finishing work. This stunning plate features a beautifully preserved Diplomystus dentatus alongside a Notogoneus osculus, both discovered within the Fossil Butte Member of the Green River Formation. A unique highlight is the natural iron banding in the matrix, adding exceptional visual character. As always, these specimens are 100% natural—no inlays, restorations, or enhancements of any kind have been applied.

Exceptional Fossil Showcase – Rare Small Stingray with Natural Knightia Association 🌟

It’s rare to come across a small Stingray (Heliobatis) of this exceptional quality—especially one perfectly preserved in association with naturally positioned Knightia. This stunning plate is 100% natural with zero restoration, showcasing what Mother Nature intended, brought to light through meticulous, world-class preparation.

What sets this specimen apart isn’t just the rarity of the ray itself—it’s the high-caliber craftsmanship in the preparation, executed with such precision and care that the integrity of every detail is preserved. Unlike many commercial pieces, this plate has not been altered. No insets. No fabricated composites. Just a clean window into the Eocene, framed by millions of years of geologic history.

📍 From the world-renowned Green River Formation, this piece is not only a collector’s dream but a paleontological masterpiece—ideal for museums, research collections, or private enthusiasts seeking investment-grade fossils.

We will be listing it soon on our website, but serious inquiries are welcome in advance. If you understand the rarity and importance of this piece, we’d love to speak with you.
