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....

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...

However, around 170 million years ago, these squid-like creatures began to build their shells in exotic, highly variable shapes. This specific ammonite is unpolished, revealing its natural coloring. *Stock photo is shown, similar piece will be...

Ferns are a very ancient family of plants. They predate the beginning of the Mesozoic era, 360 million years ago. By as early as the Triassic period, evidence of ferns related to several modern families appeared. Most modern ferns are leafy plants which grow in moist areas under forest canopy,...
