This is a natural DOUBLE trilobite fossil showing trilobites that once thrived during the Middle Ordovician Period in Wales. It is of the species Trinucleus with another small unidentified Asaphid trilobite nearby. It is on its original rock as found when broken open and is in fantastic preservation with high relif on the glabella. There is no repair as the rock is intact with no damage to the trilobite. These trilobites were alive when the first land plants emerged on the planet. The long, thin genal spines are only partially visible which is normal as these usually do not fossilize.
