Trilobites, an early arthropod relative of spiders, horseshoe crabs, and scorpions, preserved in this level of detail only occurred as a result of very sudden underwater landslides called turbidite sequences, which ravaged the early earth when the continents were still very much on the move. The contorted body positions of...

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...

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...
