Origin: Trilobites were a large group of marine arthropods, which are invertebrate animals characterized by a segmented body and hard exoskeleton (like crabs or lobsters). The first trilobites appeared over 500 million years ago in the Cambrian Period, and spread worldwide until the Permian mass extinction about 250 million years later. Their hard outer shell made them a great candidate for fossilization, and as a result they appear frequently in the fossil record—over 25,000 species have been described!

Calymene refers to a certain species of trilobites found throughout North America, Europe, and North Africa. Our Calymene trilobites were recovered in the Anti-Atlas region of Morocco, in the Ktauoa Group formation. You can order a specific size with the dropdown menu above (NOTE: the "Large" size does not come with a display case as they are too big).

Each fossil is in good condition, although minor damage and repairs are to be expected. A Certificate of Authenticity is included.

Actually, many relics are able to be owned by anyone.

Typically, museums only want to display items that are either very rare or incredibly well preserved. This leaves many items that don't make the cut, and these are able to be owned by individuals.

While the items we sell aren't "museum grade," they still carry with them the same amount of history and uniqueness. Each relic was still hand made by a person, hundreds or even thousands of years ago.

One of our core values is not to damage or alter any of the artifacts we sell.

History needs to be preserved—after all, there is a limited amount of it that survives—but it is also something to be shared with the masses. For this reason, we put our relics in sturdy display cases that are safe to handle, but are mindful that someday the relic may need to be taken out again.

No glue or resin holds the items in place. Instead, we're developed our own method for holding the relics securely in their displays using pressure alone. In fact, any of our relics can be removed in their original condition by simply opening the display case.
