Triarthrus eatoni – Ultra-Rare Ordovician Trilobite with Fully Preserved Appendages

This museum-grade fossil showcases Triarthrus eatoni, a remarkable trilobite species from the Late Ordovician period (approx. 445 million years ago), sourced from the world-famous black shale deposits of New York, USA.

Unlike most trilobites that are preserved as exoskeletons only, specimens from this locality are globally renowned for their extraordinarily rare preservation of delicate appendages – including antennae and walking legs – thanks to rapid burial in low-oxygen marine conditions.

What makes this piece truly exceptional is its “double” configuration – two individuals (approx. 1.0 cm and 1.5 cm in length) preserved together on the same shale slab, both displaying clearly visible appendages. Such specimens are scientifically invaluable and highly prized by advanced collectors.

Opportunities to acquire examples of this quality are extremely rare. Whether for a top-tier private collection or a museum exhibit, this is a once-in-a-lifetime acquisition for any serious trilobite collector.
