Trilobite Display Case & Handheld Sizes

Above: Front of Specimen Card

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.

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.
