Huge 3.5\" Two-Toned Phacops Trilobite Fossil on Matrix with Display Stand 193g For Sale

Huge 3.5\" (90 mm) Phacops / Morocops Trilobite, Middle Devonian, Anti-Atlas, Morocco

A large, beautifully prepared phacopid trilobite with a colorful two-toned exoskeleton, resting prone on its original light-gray limestone matrix. This is a genuine, naturally preserved specimen, approximately 390 million years old.

Both schizochroal compound eyes are excellently preserved, with individual lens facets clearly visible in the close-up photos. Glabellar tubercles are also clearly visible. The thorax exhibits a nice ebony-to-chocolate gradient going from the left side to the right side. The cephalon exhibits shades of rust orange to chocolatey brown. The prep work is clean and detailed throughout.

Condition: There is a small gap between the second and third thoracic segments. There is a small patch of shell loss on the bottom tip of the nose (see pictures). I could not find evidence of restoration under UV light inspection. Some mounting putty residue on the bottom of the specimen. Comes with acrylic display stand.

Measurements:

• Trilobite: 3.5 in (90 mm) nose to tail, unrolled
• Matrix: 3.25 in (83 mm) at its widest point
• 193 grams
