No creature exemplified the diverse nature of life more than the trilobite. This class of arthropods formed a staggering amount of different species throughout the Cambrian period. Today, over 5,000 different genera of trilobites have been discovered and named, with more surely waiting to be discovered.

This specimen is a trilobite from Morocco. They come from Silurian and Devonian formations and date to 350,000,000-400,000,000 years old.

Trilobite Sizes:

• Small Riker Box - Roughly 5mm to 1cm in length, each trilobite is secured in acrylic specimen jars and housed inside our classic, glass-topped riker display cases. The cases measure 4 1/2" x 3 1/2". Genus is broadly categorized under Phacops africanus. A small information card is also enclosed that also serves as the certificate of authenticity.
• Large Handheld Specimens - 2" and up, these larger specimens are too big for a riker box and will ship in our sturdy cartons. Genus is typically Flexicalymene though broadly categorized under Phacops africanus. A small information card is also enclosed that also serves as the certificate of authenticity. And yes, you will want to hold them. That's a-ok!

Please Note: Each trilobite is a unique individual. Positioning and coloring will vary widely. Some are flat and some are curled in a ball-like position. This is completely normal. As pictured, large trilobites may show some signs of repair.
