For over 250 million years, trilobites were one of the most successful species on the planet. Now, there are none... except for the fossils.
These small trilobite fossils were found in Morocco, the world's center for trilobite digging. While they aren't common worldwide, there are enough of these trilobites that they're available for private collectors. Each of these fossils is from a trilobite that lived hundreds of millions of years ago during the Devonian period, and now it can sit on your shelf.
These average in size (the whole piece, not the trilobite itself) about 2" long.
