Trilobite - Unknown Species This trilobite has a different morphology from the commonly seen Phacops and Flexicalymene, and the matrix also has a unique stone quality, making it a rare find. This item is for enthusiasts. The compound eyes can be clearly seen, so it is unlikely to be a replica. However, there is no information about the original source, so the authenticity, location, and scientific name are all unknown. Please purchase only if you understand this. The matrix is glued to the base and cannot be removed. This is a current item, so please check the photos carefully before purchasing. We cannot be held responsible for any product defects or shipping accidents. Please purchase only if you understand this. If you have any questions, please feel free to ask! I also have Trilobites Ammonites for sale. Please take a look if you'd like!
