Description: The genus Phacops is a notable group of trilobites that lived during the Paleozoic Era, specifically in the Devonian period. These trilobites are often found in fossil collections due to their striking appearance and detailed preservation. Phacops trilobites are well-known for their large, prominent eyes, which were compound eyes with many lenses, providing a wide field of vision. The thorax (body) consists of multiple segments (typically 8 to 12) that are distinctly articulated. They had hard shells made of calcite, which is what was preserved by fossilization in these specimens. Trilobites shells would not grow with them - rather, they would molt and grow a new shell as they grew. This means a single trilobite might have left several fossils behind as it grew larger!

Because they are so large the amount of detail on them is simply amazing. These Trilobites have so much texture and detail to them you can truly see how they must have looked so many millions of years ago. Their matrix have not been overly prepared so they still contain an earthy roughness that adds to their age and natural feel.
