This specimen is a 500 million year old trilobite fossil from the Middle Cambrian period. Specifically a Paradoxides species, this beautifully preserved fossil exposes its semicircular body with free cheeks ending in its long, narrow, recurved spine. Because this fossil is not free standing, we will be sure to include...

Museum-quality, fossilized and calcified ammonite shell with an iridescent, opalized shimmer displaying hints of vibrant red. The fossilized shells of Ammonites are typically spiral-shaped, very much like that of the Nautilus. However, around 170 million years ago, these squid-like creatures began to build their shells in exotic, highly variable shapes....

Paradoxides is a genus of large to very large trilobites found throughout the world during the Mid Cambrian period.It has a semicircular head, free cheeks each ending with a long, narrow, recurved spine, and sickle-shaped eyes, providing almost 360° view, but only in the horizontal plane. Its elongated trunk was...

Fossilized psuedomorph of calcite after ammonite halve to reveal the internal chambers lined with calcite crystals.

Brittle stars or ophiuroids are echinoderms in the class Ophiuroidea closely related to starfish. They crawl across the sea floor using their flexible arms for locomotion. The most famous Jurassic deposit in the world, is found in the Solnhofen, and Eichstatt of Germany. Limestone that make up this formation were...
