This is the kind of trilobite that every collector dreams about! It is a beautiful Triarthruseatoni from the Lorraine Group, Whetstone Gulf Formation of upstate New York. This inflated trilobite was prepared slowly, hoping against hope to expose some soft parts of the trilobite. Although only one in hundreds(?) of trilobites in general have traces of soft parts preserved, this specimen was one of the lucky ones! A very distinct row of appendages are exposed - these legs are VERY EASILY seen in the photos and with the naked eye. There have been very, very few trilobites ever found in the fossil record with this much detail of the delicate soft parts. This is a very collectible example of a trilobite displaying a rarely-seen row of appendages.
